How can i implement the following constraint in cplex - i am attaching the constraint equation

Si =  set of all games in which the main toy is i

Hi,

what about anything like

int I=3;
{int} S[i in 1..I]=asSet(1..i);

dvar boolean Z[1..I];

subject to
{
forall(i in 1..I) sum(j in S[i]) Z[j]<=1;
}

?

regards

Hello alex,

Thanks for your reply. Actually the number of toys i.e. i is around 20 and j (games) around 90 and through 1 toy we can play 8 games or by some toys we can play only 1 game,2 games or sometimes 10 games.

Hi,

you could start from the provided example by changing the values of l and S
