Dynamic Programming Problem

I want to develop a small application in ABAP WebDynpro like------
1>it takes the name of a DDIC table as input and then displays the data as a tabular form
2>If I modify the data in the displayed table and then press the save button the data will be updated and saved in the DDIC transparent table
I have reached upto 1 but can't proceed towards 2 . Can anybody help me?

Hi Sarbajit,
You know how to create editable columns in Table.IF you know how add then add a button to the table name it as Save.
You have OnEnter event for Editable columns.So implement this and read the modified data from table.When you press save button again you have Event Onsubmit of Button here write the logic to update the modified data to the Table.
If you are using ALV then check this Blog.

Dynamic Programming - RTTC - Appending lines

I give up! Maybe someone else can help me with this Dynamic Programming problem.
I am using RTTC to create an itab. Now I want to append lines and for some reason can't seem to crack the syntax I need.
My latest attempt looks like this...
            FIELD-SYMBOLS: <table> TYPE ANY TABLE,
                           <row> TYPE ANY.
            lo_sdescr      = cl_abap_structdescr=>create( lt_components ).
            lo_tdescr      = cl_abap_tabledescr=>create( lo_sdescr ).
            CREATE DATA lr_alloc->alloc_table TYPE HANDLE lo_tdescr.
            CREATE DATA lr_struct TYPE HANDLE lo_rdescr.
            ASSIGN lr_alloc->alloc_table->* TO <table>.
            APPEND INITIAL LINE TO <table> ASSIGNING <row>.
The syntax check I get on the APPEND statement is "You cannot use explicit or implicit index operations on tables with type "ANY TABLE".
All the doco and examples I can find use a simple "SELECT * ... INTO CORRESPONDING FIELDS OF TABLE <table>" syntax which it not what I need to do.
Any help it appreciated.
Thanks

Hello Graham

Help with dynamic programming, knapsack problem

Hi, I wrote a code to solve the knapsack 0-1 problem by dynamic programming. At a certain point, around 30 max capacity, the code stops adding new values based on the incrementing max capacity and item values. I have no idea why, it finds the correct solution until the max capacity of the knapsack gets to around 30, and then the answers are screwed up. My code is below. Thanks in advance for the help!
     public Knapsack packDP(int capacity)
          //initialize 2d array
          Knapsack [][] knapsackSolutions = new Knapsack[safe.size() + 1][capacity + 1];
          //fill 1st row and 1st columns with empty knapsacks as sentinel values
          for (int i = 0; i <= safe.size(); i++)
               knapsackSolutions[0] = new Knapsack();
          for (int j = 0; j <= capacity; j++)
               knapsackSolutions[0][j] = new Knapsack();
          //each row of the 2d array represents an item. for loop to calculate solutions for each item
          for (int itemNum = 1; itemNum <= safe.size(); itemNum++)
               Item currentItem = safe.get(itemNum - 1);
               //get optimal solutions for each weight value in the current item row
               for (int weight = 0; weight <= capacity; weight++)
                    if (currentItem.size <= weight)
                         System.out.println("weight = " + weight);
                         if ( (currentItem.value + knapsackSolutions[itemNum - 1][weight - currentItem.size].value) >
                                   knapsackSolutions[itemNum - 1][weight].value )
//create a new knapsack with the new item
                              knapsackSolutions[itemNum][weight] = new Knapsack(knapsackSolutions[itemNum - 1][weight - currentItem.size], currentItem);
                         else
                              knapsackSolutions[itemNum][weight] = new Knapsack(knapsackSolutions[itemNum - 1][weight]);
                    else
                         knapsackSolutions[itemNum][weight] = new Knapsack(knapsackSolutions[itemNum - 1][weight]);
                    count++;
          //return last item of the 2d array, which is the optimal solution for the capacity
          return knapsackSolutions[safe.size()][capacity];

Dynamic Programming Change Making Problem - Need Someone to Review

I've created a dynamic program in which you can input any amount with any given coin denominations and it should output the least amount of coins needed to solve, HOWEVER, there are some glitches I was hoping some of you could point out and correct. Here's the code for my main method and the code for my instance methods.

1) Ask a specific question, nobody is going to debug your program for you
2) Avoid the word "Dynamic", especially if you don't know what it means.

Download a special kind of internal table (dynamic programming)

Hi guys,
with dynamic programming, i've created a complex internal table of this type :
KNA1                          |
KNB1                          |
GS_CUSTOMERADDRESS            |
GS_CUSTOMERGENERALDETAIL      |
The declaration of the internal table is :
TYPES: BEGIN OF gty_record,
        table TYPE tabname,
        dataref TYPE REF TO data,
       END OF gty_record.
This means that each line, has a different line-type. In the first field of the table, i have the name of the structure. In the second, the data-part (in debug double click on leads to structure contents - field by field).
The structure KNA1 contains C and packed (P) fields also so when i pass the internal table to FM GUI_DOWNLOAD, i have this short-dump : UC_OBJECTS_NOT_CONVERTIBLE.
Is there a way to solve this problem quickly?
The goals is download all data of a customer into a local file. Data is distribuited on different structures, readed by standard bapi 'BAPI_CUSTOMER_GETDETAIL2'. This file will be read in another program, of another system.
Any hints/suggestion will be appreciated.
Thanks a lot.
Andrea

Hi Sandra,
thx for you suggestions.
About your answer :
" Or use a DO. ASSIGN COMPONENT sy-index OF STRUCTURE ... to loop at each field, and do whatever you want with them (using WRITE ... TO ... for example, to convert numbers into text)."
I cannot use this approach to the problem, because i should keep in mind the dimension of single fields and the blanks should be concatenated also, but RESPECTING BLANK switch of concatenate instruction doesen't exists in 4.7 abap.
Sure, i can use a workaround, but i'll have a lot of programming.
"you could use XML for instance. It's rather standard! By using CALL TRANSFORMATION ID SOURCE dataObject RESULT XML string."
This could be the solution. I've already read some posts about it before write mine. I should test it: i don't know if in 4.7 release works. So i could transform the internal table to xml and save to text file.
But then, how i can read xml string and mapping again in this special kind of table ?
Is CALL TRANSFORMATION ID SOURCE XML String RESULT Dataobject instruction sufficient to perform this task?
Thanks a lot

Dynamic Programming - subsequence counting

I have two string arrays (X and Y) and I want to count the number of times that a sequence X appears as a subsequence of a sequence Y by using dynamic programing. Could you guys give me some ideas about how to create the DP table?
thanks

black_makeba wrote:
yes, this is a java programming. And the task is to figure out the algorithm. If I knew the algorithm, Coding would be trivial. So I am asking for any ideas about the algorithm.I have a weak spot for problems like this so here's a solution but I'm not sure it qualifies as "dynamic programming" in your assignment.
You start out with an X string like "abcd". We call this string X(0) because it's in its initial state. Now if the first letter "a" has been found the string is called X(1) which is "bcd" (the first letter has been found and is no longer of interest). When the X(0) string "abcd" has advanced to X(4) all letters have been found.
Example:
X(0): "abcd" - initial string
X(1): "bcd" - first letter found
X(2): "cd" - second
X(3): "d" - third
X(4): "" - whole string found
In the general case you have strings from X(0) to X(N) where N is the number of letters in the original X string.
Now you consider each letter in the Y sequence from left to right and for each letter you create an X(0) string. You may also have accumulated a number of X strings in other states like maybe five X(1) and four X(2) etcetera. You have a look at the current letter in the Y sequence and check if the X(0) string can be advanced to X(1). If not you discard it. Once a string is in X(1) it's never discarded. Then you also check all other X strings and see if you can advance them. You never advance a string beyond the X(N) state. This proceeds to the end of the Y sequence when the number of X(N) strings tells you how many hits there were.
Now here comes what I would call a "dynamic programming" strategy. In the above algoritm you keep all X strings of all states but you don't have to. You only need to know how many X strings you have in each state because they all advance too the next state in unison. So you get a table with one entry for each X state. The entry holds the number of X strings in that state.
What you need to figure out is how to update the X state table as you consider each letter in the Y sequence. The entry for X(N) is the number of hits.

Dynamic Programming with 2-D Arrays Possible in Oracle 10g or not?

Hi all,
Is there are 2-D arrays in Oracle? and when not, how can I implement any Dynamic Programming Algorithm (An [Knapsack Problem|http://en.wikipedia.org/wiki/Knapsack_problem] ) on data that I have
Thanks in advance
Edited by: ZiKaS on Dec 28, 2008 7:10 AM

Hello,
By combining single dimension collections you can build 2,3 or x dimension matrix:
Declare
type typ_int is table of integer index by binary_integer ;
type typ_tab_int is table of typ_int index by binary_integer ;
my_table typ_tab_int ;
Begin
for i in 1..10 loop
    for j in 1..5 loop
      my_table(i,j) := i * j ;
    end loop;
end loop;
End;Francois

Hello
I need to write an algorithm on this following problem
Partition vertex set V into two sets V1 and V2, so that number of edges E(V1) - E (V2) is as small as possible.
I need to use dynamic programming..... like knapsack problem,array will consists of rows n col where rows will be vertices and column as edges.
Also degree of vertex is used for solving this problem.
I need the solution urgently,
Please help.

Also, your chances in getting helpful answers from anyone increase dramatically when you spell words fully. Take "n u r" for example, that's "and you are", and "u" is "you".

Help needed regarding Dynamic Programming

Hi,
While doing dynamic programming , we bind the context variable with two types of
values .
1 . ddic
2 . extern
My doubt is in which case we should use ddic and where to use extern .
Can anybody help me out regarding this.
Thanks a lot.

Hi Ki,
Predefined, Web Dynpro UI-specific, and user-defined Dictionary types all have the
prefix ddic:.
wdContext.getNodeInfo()
.addAttribute(

we have C++, java, C#, etc as OOP languages.
ABAP has also implemented the OOP technology.
it uses classes, methods and interfaces instead of functiongroups and function modules.
As part of SAPs long-standing commitment to object technology, Release 4.0
of R/3 will contain object-oriented enhancements to the ABAP programming
language. SAPs object strategy is based on SAP Business Objects and now
covers modeling, programming, interfacing, and workflow. By using principles
like encapsulation, inheritance, and polymorphism, the object-oriented
extensions of ABAP will support real object-oriented development. This will
result in improvements in the areas of reusability, maintenance, and quality of
code. SAP offers an evolutionary approach toward objects which leverages
SAPs own and its customers investments in existing business processes,
functionality and data.

DYNAMIC PROGRAMMING IN WEBDYNPRO ABAP.

Hi Experts
How to create input field dynamical and when i click on the input field drop down ui should display,If i click n time the input field that many drop down should be displayed this should be done using dynamic programming.
Waiting for Reply.
Thanks & Regards.
kittu

Hi,
Please search before posting.. discussed many times.
To create Input field dynamically, follow like this...
DATA LR_CONTAINER TYPE REF TO CL_WD_UIELEMENT_CONTAINER.
DATA LR_INPUT TYPE REF TO CL_WD_INPUT_FIELD.
DATA LR_LABEL TYPE REF TO CL_WD_LABEL.
DATA LR_TABLE TYPE REF TO CL_WD_TABLE.
DATA LR_BUTTON TYPE REF TO CL_WD_BUTTON.
DATA LR_GRID_DATA TYPE REF TO CL_WD_GRID_DATA.
DATA LR_FLOW_DATA TYPE REF TO CL_WD_FLOW_DATA.
DATA LR_MATRIX TYPE REF TO CL_WD_MATRIX_HEAD_DATA.
LR_CONTAINER ?= VIEW->GET_ELEMENT( 'ROOTUIELEMENTCONTAINER' ).
CALL METHOD CL_WD_INPUT_FIELD=>NEW_INPUT_FIELD
EXPORTING
BIND_VALUE = ATTRIBUTE
ID = ATTRIBUTE
RECEIVING
CONTROL = LR_INPUT.
lr_matrix = cl_wd_matrix_head_data=>new_matrix_head_data( lr_input ).
lr_input->set_layout_data( lr_matrix ).
LR_CONTAINER->ADD_CHILD( LR_INPUT ).
ENDIF.
Cheers,
Kris.

Submitting a dynamic program with layout name

Hi,
I searched many blogs and the SDN forum but couldn't find a solution.
I need to know the layout fields of an ALV report for a later usage. Let me explain it with code:
I used below code to extract data of a dynamic program.
cl_salv_bs_runtime_info=>set(
EXPORTING display = abap_false
    metadata = abap_true
    data     = abap_true ).
Submit (program) USING SELECTION-SET variant EXPORTING LIST TO MEMORY
            AND RETURN.
TRY.
      cl_salv_bs_runtime_info=>get_data_ref(
IMPORTING r_data = lf_ref ).
      ASSIGN lf_ref->* TO <lt_data>.
    CATCH cx_salv_bs_sc_runtime_info.
      MESSAGE `Unable to retrieve ALV data` TYPE 'E'.
ENDTRY.
cl_salv_bs_runtime_info=>clear_all( ).
CREATE DATA lf_ref1 LIKE LINE OF <lt_data>.
ASSIGN lf_ref1->* TO <lt_line>.
What I need is to submit program with a (known) layout. If it is not possible, how can i modify the ALV report to fit a layout's display properties. (If I can manage to get -dynamic program- layout's visible fields, it will work too.)
Thank you.

Hi ,
Check this LINK you can take help from this
create dynamic varient and pass to Submit program .
[how to create a variant dynamically and get it?;
OR :
you can use function module to get layout names and reprot
ranges: lr_report for ltdx-report,
          lr_handle for ltdx-handle,
          lr_log_group for ltdx-log_group,
          lr_username for ltdx-username,
          lr_variant   for ltdx-variant,
          lr_type      for ltdx-type.
call function 'LT_VARIANTS_READ_FROM_LTDX'
    exporting
      i_tool          = r_tool
      i_text          = r_text
    tables
      et_variants     = rt_variants
      it_ra_report    = lr_report
      it_ra_handle    = lr_handle
      it_ra_log_group = lr_log_group
      it_ra_username = lr_username
      it_ra_variant   = lr_variant
      it_ra_type      = lr_type
    exceptions
      not_found       = 1
      others          = 2.

Java Programming Problem

Hi all,
I was looking for this java programming problem which had to do with a large building and there was some gallons of water involved in it too somehow and we had to figure out the height of the buiding using java. This problem is also in one of the java books and I really need to find out all details about this problem and the solution. NEED HELP!!
Thanks
mac

Yes, it will. The water will drain from the bottom of
the tank until the pressure from the water inside the
tank equals the pressure from the pipe. In other
words, without a pump, the water will drain out until
there is the same amount of water in the tank as in
the pipe The water pressure depends on the depth of the water, not the volume. So once the depth of the water inside the pipe reaches the same depth as the water inside the tank it will stop flowing. This will never be above the height of the tank.
I found this applet which demonstrates our problem. If you run it you can drag the guy up to the top, when water in his hose reaches the level of the water in the tank it will stop flowing out.
