N-puzzle problem
Hello,
I need the code for the n-puzzle problem using the branch and bound algorithm. I have found any other implementations (A*, deepth, etc.etc.) but I can�t found the branch and bound solution.
Any help will be really important for me.
Thank you in advance.
Thank you very much but in this link I can�t see the code of the solution for the n-puzzle (using branch and bound algorithm)
Actually I�m not a student, hehe, sorry about the confussion.
Any other help please?

Hi!
I want to slove 8 puzzle problem using java code.
Can anybody tell me how to solve this or either give me the link or source code where i will get idea about this.
ThanksOver the years I have found that ESP (Extra Sensory
Programming) skills are very useful when dealing with
users or business analysts who expect you to be able
to program exactly what they want without them needing
to actually tell you anything.I find they get madder ( eh? ) when you tell them that no, you cannot read their mind and program the computer just to do exactly what they want. Also funny how they think a task is somehow simplified if "it only occurs sometimes" ... damn them. -
Hi guys;
for those raedy to rise challenges i present this problem... Any ideas to solve it are welcomed..some code would be a generous action from your part...
SHUTTLE PUZZLE
The SHUTTLE PUZZLE of size 3
consists of 3 white marbles, 3 black
marbles, and a strip of wood with 7 holes.
The marbles of the same color are placed
in the holes at the opposite ends of the
strip, leaving the center hole empty.
INITIAL STATE: WWW BBB
GOAL STATE: BBB WWW
To solve the shuttle puzzle use only two
types of moves. Move 1 marble 1 space
(into the empty hole) or jump 1 marble
over 1 marble of the opposite color (into
the empty hole). You may not back up,
and you may not jump over 2 marbles.
A Shuttle Puzzle of size N consists of N
white marbles and N black marbles and
2N+1 holes.
Write a program that will solve the
SHUTTLE PUZZLE for any size N(*10)
and display the board after each move.
Use W to represent a white marble and B
to represent a black marble and a blank to
represent the empty hole. Test your
program for N=3 and N=4.
Sample Run
N = 3

Hi there,
I'm making a puzzle-type game that has the ability to solve itself. I want to put a small delay before each move so I placed a
try{Thread.sleep(sleeptime);}
catch(InterruptedException e) {}
before the repaint call. The problem is that this is only delaying the re-paint not the other computations so that when it does repaint, after the specified delay, it could have made over a hundred moves instead of one. Any help would be hugely appreciated as this is the final piece of the program and I just want it finished.
Thanks
MarkMay be, in this way:
//in thread where you perform calculations
//calculations finished
try
sleep(sleepTime);
catch ....
synchronized(yourGUIpanel)
notify();
//other thread
while(true)
synchronized(yourGUIpanel)
try{
wait();
yourGUIpanel.repaint();

I am using vs2008 and have created a crystal report (windows application). The data shows up correctly on the report (detailed section) but when I creat a chart all of the values appear to be zero. I created the chart in the report header, using a line type chart and for the data, using the chart expert I selected for each record, and also selected a single field for (Show Values). The single field is a number type and is displayed correctly in the detailed section of the report. It is a simple integer that ranges from 100 to 900. In my c# program I create a DataTable and then write out an xml file and an xmlschema file. I used the xml schema file to create the report. When the report is generated I create a new datatable and read the xml file into a dataset. I then create a data table from this dataset and use this as the report data source, crystalReport.SetDataSource(DataTable). Again all of the data shows up correctly in the report, just problems with the chart, always seems to display a line of zeros.
Thanks Paul.I was not able to move the report into a page header or footer but am thinking when the xml data is read in it is treating all columns like a string. I have 2 xml files that get created when the dataset is filled by using the datatable.writeXMLSchema and datatable.WriteXML. The WriteXMLSchema was used to create the report and does specify integer types. I think I will try to create a globabl type dataset that stays available during the windows session and just use the data set instead of saving and loading xml files during runtime.

Puzzling problem mounting some partitions from drive connected via airport
I have an external drive with three partitions connected to my airport. Under Tiger, the mounting process for all those partitions was seamless and never failed. As soon as I upgraded to Leopard, however, everything fell apart. Now I can't mount two of the three partitions at all.
When the external drive is connected directly to my MacBook Pro, each partition mounts routinely. When I connect it via my Airport Extreme, the finder window shows that I am connected; but when I attempt to access the partitions on the drive, I get this error message: 'The operation cannot be completed because the original item cannot be found.' I get the same error message for each of the first two partitions on the drive and can mount only the last partition.
When I attempt to mount the partitions manually via the Go menu in the finder, I get essentially the same result: error messages for the first two partitions saying that they cannot be mounted and a normal mounting of the third partition.
Any ideas or clues as to what is actually happening here would be most appreciated. It's very frustrating to have lost access to my backup drive purely by upgrading to Leopard and not find any obvious way to regain it.Thanks, but I have no problem accessing the drive. All I have to do is plug it directly into my laptop using either USD or Firewire. The problem is with accessing it via Airport so I can run my normal backup routine as I did under Tiger without first a lot of fiddling with cables. After all, the result of installing Leopard shouldn't have been to decrease functionality, should it?
With a direct connection, everything functions normally. With an Airport connection, nothing functions. None of the partitions show up on the desk top, none show up when I run disk utility, and -- as explained before -- I cannot even mount two of the three partitions manually. I've also noticed now that, when I do mount the one partition that will mount, it freezes the finder when I try to unmount it. After that I have to relaunch the finder in order to regain functionality.
It seems pretty obvious that the whole mess is a function of Leopard and Airport somehow, but I'm just at a loss to narrow the problem down any further. -
...puzzling problem with PHOTOSHOP CS...
...still can't import layered PHOTOSHOP files into FCP. Layers are discarded and the imported image is flat. Does anyone else have this problem? Thank You
...this version of PHOTOSHOP for 2 years now, with countless layered files animated in FCP and as of last week I can't. Maybe since the TIGER 10.4.11 and then the upgrade to LEOPARD something changed. I just can't figure it out. I've ruled out an FCP or a PHOTOSHOP CS problem because my whole drive has just had an erase and complete re-install. Something insidious is at work here.

Hey all
So I have a puzzle that doesn't want to work properly. I have it setup so when all six pieces are dragged onto their respective spots, the movie goes to frame 2, but when I drag all the pieces properly and the scores add up to 6, the action of going to frame 2 doesn't occur, but if I pull a piece off, and the score equals 5 the action occurs!?!?!?!?!?!
There are 6 pieces named tl, tm, tr, bl, bm, br and those get dragged onto their 6 respective mcs (drag_tl etc.).
I have no idea why this is happening. Any help would be appreciated.
Thanks
Here's the link: superbean_puzzle
...one more thing, is there a way to make the link disply at 100% instead of full screen?
Thanks some more

Puzzling Problem with getParameter
This is weird.. I shouldn't have any problems with getting the params I've set in the APPLET tag, right?
Well I do - and it's very annoying
Where I call it (in the constructor) the code looks like this:
if(getParameter("URL") != null)
myUrl = getParameter("URL");
When I run in the appletviewer, or try just opening the HTML page with a browser (IE), I get the
following error:
java.lang.NullPointerException
at java.applet.Applet.getParameter(Applet.java:158)
at Configur8Applet.<init>(Configur8Applet.java:32)
Line 32 is the first line of my submitted code
Heeeelp!I don't know, but I'd expect that in the constructor the parameters aren't available yet. The applet environment has to instantiate your applet and then make the parameters available to it.
I'd suggest moving the troublesome code to the init() method. -
Puzzling problem - DW doesn't see recordset it created
NOTE: I'M STARTING THIS THREAD OVER IN THE DW APPLICATION
DEVELOPMENT FORUM... ADMIN, PLEASE DELETE THIS THREAD... SORRY FOR
THE DOUBLE POST.
I hope that there is someone out there that can help me with
this... I've looked all over online and can't find an answer to
this anywhere.
I'm using DW MX 2004 (7.0.1), ASP...
I get this message when trying to add the Update server
behavior... "before using this server behavior, please create a
Recordset"
I receive this message even though there is already a
recordset defined. I've even successfully created a brand new
recordset, using the DW tools, and it STILL gives me this error.
To answer some questions that you may ask during
troubleshooting...
Are there any error messages (red exclamation points) in the
bindings window? No.
Does the recordset appear in the bindings window? Yes.
Have you tried rebooting? Yes.
Can anyone please help me? I'm really stuck on this?
Thanks so much.Yes there are settings of the mobile that take settings from user profile.

Problem writing external file to externally mounted disk in Windows
Folks,
I've got a puzzling problem with a simple OWB mapping where I'm dumping the contents of a table to an external file.
Versions are OWB v 11.2.0.2 64-bits on Oracle RDBMS 11.2.0.2 Windows 2007 64-bits Enterprise Server.
When the external files module is hooked up to a location that points to a local disk and directory on the OWB-server, everything works fine - files are created and written.
When the external files module is hooked up to a location that points to a mounted disk on another Windows 2007 64-bits Enterprise Server, I get +"Invalid Path for target file, check if connector is deployed correctly".+
The "File System Location Path" in OWB is set to "N:" (no slashes either way). "Test Connection" reports OK.
I've given both the Oracle os-user and "Everyone" (for good measure) all rights on the mounted disk, and I can see that the generated package code is using the correct Directory, and the Directory Path is the correct one on the server. The mounted disk (N:) should appear as a local disk to Oracle as far as I can see. I'm able to create and delete files on the disk using command line on the OWB/DB-server.
I'm scratching my head on this one....then mapped that share as a network drive (N:) on server A (the OWB/DB-server)I think that problem was with different accounts used for run Oracle database (usually database instance run under SYSTEM account) and which you used to map share (it was interactive session). Even when you made this map persistent (enable "Reconnect at logon" option during mapping) you don't grant access to this drive to other accounts (including SYSTEM ) - this drive will not be visible to other users.
I think it is possible to create "persistent" network drive mapping for Oracle database context with specification non-SYSTEM account (domain or server local) for running Oracle database instance (and Oracle Listener service).
Also it seems there is a workaround to access mapped network drive under SYSTEM account:

Problem opening a particular PDF document in ALL browsers
I have a problem a PDF document in all browsers.
I have a mail order account online and I am trying to open one of my statements by clicking on the PDF logo.
A new window opens and is either blank or tells me it cannot load (depending which browser used). When the new window opens the address in the browser is an IP address / name of the company / document number.PDF
I have contacted the company but they tell me to either download the latest Adobe Reader (which I have), and try a different browser (which I have).
I have tried changing settings in all browsers as per instructions found on other sites, and I can open PDF docs from other sites and my pc no problem. This tells me that the problem lies with the company, yet they cannot seem to resolve.
Does anyone have any ideas or can shed light on this puzzling problem?
So grateful, thanks.Can you try to download that PDF to your local disk, and open it from there?

Problem with random number generation
hey forum, i wonder if anyone can help me out with a small problem with my university coursework (yep its homework!!!)
heres my problem, i am writing one of them 8 puzzle problems (the one based around sam lloyds 15 puzzler), i can successfully generate one random sequence of numbers with no duplicates, but whenever i call the random method again it keeps producing the same results
heres the code
in my main class file
if(e.getSource() == randomButton) {
new RandomPuzzle();
System.out.println(random.randState);
//startStateString = new RandomPuzzle();
}heres my number generator class file
import java.util.Random;
import java.io.*;
public class RandomPuzzle
/** Base Random number generator */
Random rn = new Random();
/** Puzzle holder */
byte b[];
long number = 0;
String randState = "";
/** Default constructor */
public RandomPuzzle() {
rn.setSeed(number);
b = new byte[9];
randState = randomString();
/** Provide range for generation */
public int rand(int lo, int hi) {
int n = hi - lo + 1;
int i = rn.nextInt() % n;
if (i < 0)
i = -i;
return lo + i;
/** Set size for array */
public int rand( int hi){
int n = hi;
return n;
/** Check for duplicate values within the same configuration */
boolean valueExists( byte value ) {
int i = b.length;
boolean exists = false;
for( int j = 0; j < i; j++ ){
if( b[j] == value )
exists = true;
return exists;
/** returns the actual string */
public String randomString(int lo, int hi) {
int n = rand( 9 );
//boolean valueEntered = false;
for (int i = 0; i < 9; i++) {
boolean valueEntered = false;
byte temp = (byte)rand('0', '8');
while( valueEntered == false ) {
if( !valueExists( temp ) ) {
b[i] = temp;
valueEntered = true;
else
temp = (byte)rand('0', '8');
return new String(b, 0);
/** calls above function */
public String randomString() {
return randomString(0, 8);
}i've tried for hours to work this out, but i am stumped. if anyone can point me in the right direction, maybe point out the problem code and give one or two tips i would be forever in your debt
thanx in advance
korbitzthanx for the help paulcw, but when i removed the seed code it done the same
but i added this to my main class and now it works fine
if(e.getSource() == randomButton) {
RandomPuzzle temp = new RandomPuzzle();
System.out.println(temp.randState);
//startStateString = new RandomPuzzle();
}thanx again for your help -
I wrote about my problems with IE earlier, and was able to
fix the DataSet problems on my own. Now that that is fixed, I am
trying to resolve the issues with the menu-bar and the effects. The
menu problems, which stack horizontally instead of vertically, are
site-wide. They probably have to do with modifications I made, but
which ones? The problems make the menus difficult to use.
The other really puzzling problem are the effects that is
supposed to slide new text onto the page. If you click on each of
the three controls between the image and the text, you'll see that
only one works properly, although they all work fine in other
browsers.
I hope someone can help me with this. I'm banging my head
against the wall trying to figure it out.
The page is at www.kateswork.com/projects/portfolio1.htm
Thank you!Okay, I have read the styling examples you referenced. The
problem I'm experiencing in IE for my menu bar is not the same as
the problem described in the those examples. The text in the
auto-width example says, 'In IE the sub menus now have white gaps
between the menu items!' But on my page, the IE problem isn't white
gaps, it's menu alignment: the submenu items align horizontally
instead of vertically. Not surprisingly, the workaround featured
there does not fix the problem on my page.
For reference, my test page is now at
http://www.kateswork.com/projects/portfolio1.1.htm
Thanks again for all the help so far. I've gotten some good
answers here, but two problems remain: the misalignment of sub-menu
items, and the refusal of the upper slide effect to work as it does
in the other browsers. I'm beating my head against the wall.
