Min max with Alpha Beta pruning

Hey I would like to add Min max with Alpha - Beta pruning for my tic tac toe game. If you know some sort of tutorial or anything please let me know. After I complete I'm going to make a complete guide to make a Tic Tac Toe game with a really nice GUI, Music, AI, and Network capabilities. I have the game made so far. I'm going to rewrite it with interfaces and clean up the code a lot then create the guide, but before I do all this I want to create and AI for it.

I suppose that since, other than reading a summary on Wikipedia, I
don't know what a 'minimax algorithm' is and have never tried to
implement one I should not make fun.The idea is quite simple: your best move e.g. in a board game is my worst
result and vice versa. If I can minimize your best move I have maximized
my best move (and that's the move I'll play).
Now suppose my best move somewhere in that game tree turns out
to be worse than another best move of mine somewhere else in that
same tree, there is no need anymore for me to explore the rest of that
subtree. That's the alpha pruning part. The same counts for you and
that's the beta pruning part.
alpha-beta pruning reduces the number of nodes to be examined to
O(sqrt(n)) where n are all the nodes in the fully examined tree. It is
quite a nice algorithm although quite tricky too when you have to build it.
The best reference I can think of now is the old book "Data Structures"
by Horrowitz and Sahni.
kind regards,
Jos

Help in nega max+alpha beta pruning

well I have programmed a connect four which implemented minimax algorithm,but then it took 10 secs(minimum) to reply for maxdepth of 8. More over it still lost few games to online ai's which to my surprise played faster and more accurate than my program.Then by searching in books and internet I came across search funtion called as megamax with alpha-beta pruning.I replaced my minimax with this method but then it plays very bad(doesn't even see the connect 4 even if there are 3 in a row).I am willing to put my source code, pls point out my mistakes and rectify (with explanations if possible). Thank you, and also forgive me for grammatical mistakes(if any) as english is my second language.
I know alpha beta is a bit tedious thing to do(at least for me as I am doing it for the very first time).

Min/Max Planning R12

Have a real headscratcher!
Run Min/Max with this set-up:
Min/Max/Min = 826
Min/Max/Max = 826
FLM = 300
Min Order Qty = 691
The on hand is 380 and when Min/Max runs we get an order for 691 pieces. Seemingly ignoring the Fixed Lot Multiplier of 300. The thought was we would have seen an order for 900.
Run Min/Max with this set-up:
Min/Max/Min = 826
Min/Max/Max = 826
FLM = 300
Min Order Qty = 445
The on hand again is 380 and when Min/Max runs we get an order for 600 pieces because it "honors" the Fixed Lot Multiplier of 300.
Seems more like a bug then a feature. Thoughts? Thanks

Hi Stick,
As per my understanding,
In scenario 1:
=====================
Min Qty = 826
Min. Ord. Qty = 691
On Hand = 380
So On hand + Mind. Ord. Qty = 380 + 691 = 1071 which is greater than Min. Qty which is 826
So, in this case, system will not look at the FLM as Min. Ord. is compulsory to place.
===========In Second Case========
Min Qty = 826
Min. Ord. Qty = 445
On Hand = 380
So On hand + Mind. Ord. Qty = 380 + 445 = 825 which is lesser than Min. Qty which is 826
So it will follow the FLM.

ESYU: Min-Max planning을 실행하면 자동으로 ReqImport program이 launch 되지 않는 원인

Purpose
Oracle Inventory Management - Version: 10.7 to 11.5.10
REPORT:INVISMMX - Min-max planning report
EXECUTABLE:POCIRM - Requisition Import
Buy items에 대해 Min-Max(with Restock=Y)을 실행하면, 이 program은 ReqImport를
자동으로 launch 시키지 못하고 단지 po_requisitions_interface_all table에 data를
insert 한다.
하지만 사용자는 Min-Max가 실행되면 이후 자동으로 ReqImport가 실행되길 원하고
있다. 이를 위한 workaround 방법을 소개한다.
Cause
ReqImport가 Min-Max 이후 자동으로 실행되는건지, Min-Max에 의해 자동으로 실행되는지
구분할 필요가 있다.
ReqImport는 Min-Max에 의해 실행되지 않는다.
Min-Max의 standard design은 단지 po_requisitions_interface_all table에 data를 넣어
주기만 할 뿐이지 ReqImport request를 자동으로 실행시키지는 않는다.
ReqImport는 Min-Max 진행 후 실행될 수 있다.
왜냐하면 ReqImport는 주기적으로 실행되게 scheudling 되어 있거나, ADS_PO_REQ_IMPORT_TRG1
와 같은 trigger에 의해 실행된다.
일부 vision demo instances에서 위 trigger를 볼 수 있는데 이 trigger에 의해 po_requisitions_interface_all
table에 data가 insert가 되면 ReqImport가 launch 된다.
Note: 이 Trigger는 standard product이 아니므로 귀사의 instance에서는 찾을 수 없을 것이다.
Solution
1. Short-to-medium term solution at your instance:
1-1) ReqImport가 주기적으로 실행될 수 있게 Schedule 해 놓는다.
-- or --
1-2) Min-Max report(Restock=Yes) 실행 후 manual 하게 ReqImport를 실행한다.
-- or --
1-3) Min-Max와 ReqImport programs을 포함하는 Report Set을 define 하고, Min-Max 대신
이 Report set 만을 실행한다.
-- or --
1-4) po_requistions_interface_all table에 triggers(similar to ADS_PO_REQ_IMPORT_TRG1)를
생성한다.
2. Medium-to-long term solution from Oracle
ER/Doc bug을 등록하고 metalink를 통해 진행과정을 check 한다.
2-1) Enhancement Request via ER/Bug 4310485 to have Min-Max Report to fire ReqImport automatically.
2-2) Documentation Bug 4310487 to have the INV User Guide corrected that Min-Max does NOT create Requisitions,
but ONLY populates the po_requisitions_interface_all table.

Avg, Min and Max with a serious twist.....ASO

Hi,
I need to calc the Avg, Min and Max on Revenue. That's simple. However Every row of data the revenue falls into a bucket/range. For example revenue is in buckets '0 to 50' or '51 to 100' or '101 to 150' lets say. As I load data I load a '1' into a 'Count' measure depending on which bucket that row of data falls into. So I can get a total count for each bucket. So '0 to 50' might have a Count of 3. '51 to 100' might also have 3 and '101 to 150' has a 2. So my range count looks like:
0 to 50 - 3
51 to 100 - 3
101 to 150 -2
The trick is they only want the Avg, Min and Max on the rows that makeup the highest 'Count'. In this case that's 3. Problem is there are two ranges that meet this criteria. When that happens they want the Min, Max and Avg of the rows that make up the '51 to 100' bucket since it's the highest range.
I can easily get the '3' by using the Max formula. So I know what the highest bucket is. Problem is I can't figure out for the life of me, how to pass only those rows that make up the '51 to 100' bucket into the Avg, Min and Max function.....
I'm stumped and in dire need of something here. I have a spreadsheet that explains the problem better. If somehow I can get a flag on those rows I can easily Avg, Min and Max it. I just can't seem to figure out how to get a flag on only those rows of data.
I'm willing to share my mocked up example and spreadsheet and .otl and sample data etc....
Please help :)

DateTimeAxis min/max bug? Problems with consistent padding. Date Wrapping.

I have been working on a problem with a BarChart object that I've created using dynamic data.
My primary issue is that I can't seem to get the proper min/max values to set for the chart.
To solve this I manually found the min and max of the data set of Dates and set the min and max of the chart. This allowed me to finally see all the floating custom bars (each bar is rendered with a user set fill), however now if I have a bar that extends over a year change the horizontal axis labels do not wrap the date properly, so instead of 2/10 (feb 2010) being the last date, 12/09 (dec 2009) is the last date.
I've been trying to dynamically adjust the padding based upon a change event, but so far to no avail. Partially I think because I'm not sure which event for the function to fire on.
private function dateAxisGen(r:Array):void {
 var min:Number = r[0].startTime.time;
 var max:Number = r[0].endTime.time;
 const PAD:Number = 2;
 const MILLISEC_IN_MONTH:Number = 2629743830;
 const MILLISEC_IN_WEEK:Number = 604800000;
 const MILLISEC_IN_DAY:Number = 864;
 for (var i:int = 1; i < r.length; i++) {
 var o:OperationXT = OperationXT(r[i]);
 min = Math.min(o.startTime.time, min);
 max = Math.max(o.endTime.time, max);
 // Calculates the maximum range, then adds an appropriate
 // padding to the chart via extra time. TODO
 /* var range:Number = max - min;
 if(range >= MILLISEC_IN_MONTH) {
 dAxis.padding = (MILLISEC_IN_WEEK/1000000)/PAD;
 dAxis.padding = (MILLISEC_IN_WEEK/1000000)/PAD;
 } else if(range >= MILLISEC_IN_WEEK) {
 dAxis.padding = (MILLISEC_IN_DAY)/PAD;
 dAxis.padding = (MILLISEC_IN_DAY)/PAD;
 } else {
 dAxis.padding = PAD;
 dAxis.minimum = new Date(min);
 dAxis.maximum = new Date(max);
this, however, does not adjust the padding properly when an operation is removed from the list. Not to mention I still have the date wrapping error. It gives me the following error:
Cannot access a property or method of a null object reference.

Any help with my problem would be greatly appreciated.
ADDITIONAL INFO:
Alright, so I've discovered that the ONLY time the date wrapping error occurs is when the axis labels contain only the month and year, any other time it places it properly.
Does anyone know where I can report this bug?

It's clearly not impossible, just different than you expect. Create your playlist as you want it to appear in the Current tab (meaning don't dump every single song from your library in there, just the ones you want) and then save the playlist.

Look at save_absolute_paths_in_playlists in your mpd.conf.

When firefox 4 is maximized navigation toolbar overlaps with windows 7 buttons up right on the screen(min,max,restore) and overlaps with orange button up left on the screen

Hi all.
I have installed firefox 4 and i have an issue which for start i dont know if it is supposed to be so or not.
When i maximize firefox ,Navigation bar is mixed (shown below) the orange button on the upleft of my screen.Also is shown below of the 3 windows buttons (min,max,close) of the windows 7 in the upperight of my screen.
Is this supposed to be so?
I also have some screenshots if you would like to see :

Thank you for your time reading this and excuse my lame English.

Any news on this.
I think it has something to do with the add on : Tabgroups manager.
If i disable this add on then everything works normally.
Also when this add on is enabled my tabs are always below adress bar ,no matter what.

Displaying Max/Min values with time for analog signals.

I am sampling analog inputs. I simply want to display the max and min values with the time they occurred. This seems simple but I am new to LabView and can't find a Vi to do this.

Here's the code. When you run the demo program, you'll see three traces: Green is the max so far, Red is the min so far, and White is the current signal value.
As the input value cycles, you'll see the two limit values track its extremes. If you have any questions about how it works, just holler.

How to calculate Min & Max temperature with just air temperature

Hi Gurus,
I have a requirement in which I have to build a Bex Query in which I have to find the Min & Max temperature of a day if a specific date range is used in the query.I have checked the multiprovider and there is only one field available
which is "Air temperature" and it's a KF. I have built a query which will give you the temperature for the day if you give a particular date range.
My question is,is it possible for me to find the min and max temperature with just air temperature as input?
Please let me know your thoughts.
Thanks,
Raj

Hi,
You have to create two KFs for Min and Max temperatures,
In Min Temp KF definition, Aggregation Tab-->Minimum--> reference char as 0calday
In Max Temp KF definition, Aggregation tab-->Maximum-->Reference char as 0calday

Issue with min/max when vertical axis assigned to multiple series

Hi.
I have some simple charting code that is dynamically adding LineSeries to a chart as the user requests them from the gui. As each series is added the vertical axis is assigned to the series and then data is requested and assigned to the dataProvider on the series. This is all working fine however I have found that if I add a sceond series after the first series is displayed and assign the same vertical axis to the second series then the vertical axis seems to set teh min/max based only on the second series added and ignores the first series. It doesnt set to the max of both series and so I get an incorrect max set. If I add a 3rd series the same happens again and the first and second series values seem to be ignored and the axis is set based on the last series to be added.
Is this expected? Ive tried different variations of invalidating the data/series/styles to force it to refresh but I always get the same. It does refresh but based on only the values in the last added series.
What is odd is that if I add 2 series at the same time, and assign the axis to both of them and then request data for both and update the dataProvider on both of them the axis is configured correctly based on the max value of both series.
Any workarounds to make it do the right thing if they are added dynamically? Is this a bug or a known "feature"?
Any light anyone can shed would be appreciated.
I need to have the axis assigned to the series directly as I want to be able to use multiple axes. I have found that if I set the verticalaxis on the chart rather than the series then it works fine and sets the min/max based on the combined values of both series.
The vertical axis is just a simple LinearAxis.
Any help or suggestions would be appreciated.
Im using Flex 4.1
Tks
Dan

Adobe Flex LiveDocs seemed to indicate "Using multiple series in the same chart works best when the data points are in a similar range (such as a stock price and its moving average). When the data points are in numerically very different ranges, the chart can be difficult to understand because the data is shown on a single axis. The solution to this problem is to use multiple axes, each with its own range. You can plot each data series on its own axis within the same chart using the techniques described in Using multiple axes" and that link is here:
http://livedocs.adobe.com/flex/3/html/help.html?content=charts_types_11.html
I was going to tae a look at this myself, but the code posted here is quite complex, and I suspect incomplete.
If you refer to that link and still cannot solve the issue, I would try your best to boil down your code to a more simple example still exhibiting the issue, and then post that, along with any data and the simplified main app.
If this post answers your question or helps, please mark it as such.

Hello Martin:
Thanks for your input. However I am not certain we have resolved this issue adequately, or understand the principles governing the css as regards this spry menu framework 2.0 (1.0).
For example, the menu only works in IE 6.0 if the css remains in the head. I agree with your original post that it shouldn't make any difference whether the css is posted in the head or in a separate style sheet (so long as specificity issues are addressed). Both should work -- and yet it doesn't.
If the CSS is placed in the separate style sheet governing the total site, it doesn't work for 6.0. If placed at the top of the style sheet, conflicts of specificity prevent the menu from rendering properly in any of the browsers causing the rules for general links to govern the menu.   This has been verified using a cross browser testing. If the styles are placed at the bottom of the style sheet to help them take precedence, they work in all the browsers except for IE 6.
The website I am building needs to support IE 6 for a variety of reasons, and because it is catering to the non-profit community and to low income persons, I am mindful of even small differences in page weight.
So for me, at least, the issue remains baffling.
I appreciate your input, but also would appreciate the input from others, and especially Adobe Community Professionals and employees. The spry framework in this regard is not well documented. I am not certain if this is exclusively a CSS problem, if it might also be complicated by the architecture of the spry framework, or if indeed other variables are at play.
I would be my hope that in resolving the problem, other users of the this particular spry framework might also benefit.
Thanks,
Steve.

Need some help with the DOF Min Max Planning Logic

Hello All,
Morning...could someone please help us with this issue which we are facing in our production system.
We are running the Dof Min Max Planning Report at the Subinventory level and for a given item.
This item setup in this sub inventory has the Min qty : 2 , Max qty :2.
--We don't see any open orders/ requisitions in the system for this item.
--We also don't see any expected receipts for this item coming to this org/subinventory.. All the shipment lines are in Fully Received status.
--We dont see any stuck supply records in mtl_supply table as well..and also checked for the Inv Transactions interface tables as well ( MTI , mtl_material_transactions_temp)..we dont find any stuck transactions for this item, subinventory & org.
Now when we are running the Dof Min Max report is is showing the Supply Quantity as 2 and Available Quantity as 2.
Hence the Reorder quantity is coming as Zero..basically it is not re stocking the item again for this subinventory level.
Could someone please assist as to what could be reason why this Supply Quantity is showing some value when we dont see any stuck supply / expected open receipts..
What else we need to check here to get this issue resolved and to know the source of the Supply Quantity.
thanks

In the report run, what parameters are considered as Supply?, Also did you check the supply data considering your cutoff dates offset?, the item what you are talking about is a buy item? check if there were requisitions already created.

Need help with min max sql

hi all, forgot i had a user name and password and haven't needed help for quite a bit since i didn't do sql for a while but now i'm back at reporting again...
Here is a sample table as i remember it:
Item     Date     Time     Time Frame     Duration     Duration Frame
A     20100926     0     5     500     10
A     20100926     600     10     500     30
A     20100926     1500     12     100     30
B     20100926     1800     28     200     40
B     20100926     2200     6     150     70
B     20100926     2600     15     600     60
B     20100926     3600     30     200     70
Results Set (expected):
Item     Date     Time     Total Duration
A     20100926     0     1600:20     --basically max (time+duration) - min(time+duration)
B     20100926     1800     2000:00
Sorry, but. I didnt put my sql statement as I wasn't planning on posting and left it at work, but, i've been looking on internet and people say to use min/max function and i've attenpted it with it works with just this table (without grouping). But as soon as i group it the values seem to mess up.
Last i remembered it gave me:
Item     Date     Time     Total Duration
A     20100926     0     1600:30     --basically max(time+duration) - min(time+duration)
B     20100926     1800     2000:70
I think it's looking at max duration which is 30&70 and hence it retrurns those values in the result set. Is it because of the max function hence it's returning this value? any help is appreciated. thanks

Okay, here we go again, repost, hopefully okay this time:
Hi Madhu, okay, just got to work: I am using TOAD and working in Oracle 10g. Here is my table structure and the query i use to try and get what I am looking for:
There is one extra table but that is only used to link these two tables listed below so i didn't bother posting it.

Can we use MRP to plan for FERT in-house produced with PIR's & has Min/Max

Hi SAP Guru's
I have a very critical issue from the client who wants to use MIN/ MAX stock values for planning its finished products (in-house produced)
here is the details of the scenario
Client recieves 2 Excel files every week from customer
1st file contains the Weekly Demand Forecast of FERT material for next 1 year and they upload it in MD61 as PIR's BUT this value is also Inclusive of Safety stock value (ex: if weekly demand entered in MD61 as PIR is 50 and if safety stock value is 10, then actual demand is only 40)
2nd file send contains only safety stock values (for ex in this case let it = 10) to be maintained for the FERT materials
the client wants MRP to plan and trigger based on this PIR's in MD61 and Safety stock level fand plan for FERT, HALB and also ROH materials as defined in the BOM also taking into consideration the current WIP levels (Work in progress for any existing production orders currently being processed) based on the production Lead times values maintained
so what the client wants is they want to maintain 2 stock values, that is one least stock value and other higher value which if stock falls below this point, will trigger production based on the lead time and considering any WIP levels also
(for ex in this case if PIR = 50 and safety stock is 10, MRP run result client wants is = 30 and NOT =40)
so here are my questions
1. is this scenario feasible? use safety stock and min/max level for in-house produced finished which has demand PIRs in MD61 at the same time?
2. Also due to SOX complaince regulations, the client does not want to change the forecast values in MD61, so is it possible to make some settings so that forecast is corrected by WIThOUT including the safety stock value in it? ( for ex: in this case as = 40 only and NOt as 50)
3. which all settings should i maintain like for MRP type or lot size or stock qty levels or anyother customizations if any required so that when we run MRP, can it ignore the safety stock value and generate the client desired output?
thank u verymuch for your time & expert advice in advance

Hi Chakri,
This is not possible as per standard functionality. MRP always creates proposals for the shortage quantity of the safety stock. We have used the user exit in the plant level MRP run to exclude both plant and safety stock in the net requirements calculation.
You have to write logic to convert the safety stock into plant stock in the user exit so there will be no additional procurement proposals...you can create custom indicatar in materail master or linked any existing indicator like MRP group to the user exits so the MRP will checks this and will not create proposals for the selected parts.
If you have any questions then please inform.
