set of Number of matches with respect to each player::

A can play three matches {1,2,3}

B can play five matches {1,2,3,4,5}

C can play eight matches{1,2,3,4,5,6,7,8}

D can play four matches{1,2,3,4}

E can play six matches{1,2,3,4,5,6}


Now my problem is how to assign

[N][A][3 matches]

[N][B][5matches]

[N][C][8matches]

[N][D][4matches]

[N][E][6matches]

[D][A][3 matches]

[D] [B][5 matches]

....

.... so on

How can i access the above in generic way  please help

Hi,

have you tried with tuple instead of using arrays:

tuple DataInfo
{
    {string} city;
    {string} player;
    int match;
};
{DataInfo} pData = {<"N", "A", 1>,<"N","A",2>,<"N","A"3> ...}

Thanks for your reply but i can't use tuples because my data is very huge around 2000 combinations of this city, player and match

Here is recommendation how to fill in tuple:

{string} Cities = {"City1" ,"City2", "City3"};

{string} Players = {"Player_1", "Player_2", "Player_3", "Player_4", "Player_5"};

int nMatches[Players] = [ 3, 5, 8,4, 6];

tuple _DataInfo_
{
    string city;
    string player;
    int nMatch;
}  

{_DataInfo_} dataInfo = {<city, player, n> | city in Cities, player in Players, n in 1..nMatches[player]};

An example opl\examples\opl\transp explains the advance of tuple in relation to matrix approach.

Thanks for your reply

Cities are in range and players are also in range

Cities = 1..5;

Players = 1..100;

Matches  is a vector  [ 3, 5, 8,4, 6];

int A = 20;

int B = 60;

range L = 1..A;

range S = 1..B;

int C[L][S] = [3,5,4,8,6,12,45,65,7,5];

tuple _DataInfo_ {

  int A;
  int B;
  int C;
}
{_DataInfo_}dataInfo = {<m,n,s>| m in  1..A,n in 1..B,s in 1..C[L][S]};

L and S are range
