Hi, is there anyone know how to write an objective function, which is a summation with index value as a decision variable?? Something like below:

tuple Arc {
  int FromNode;
  int ToNode;
}
{Arc} arcs = ...;
float ArcCost[arcs] = ...;

dvar int+ successor[0..2*numJobs] in 1..2*numJobs+1;

minimize
    forall (a in 0..2*numJobs) sum ArcCost[<a, successor&#91;a&#93;>];

Thanks.
Anthony

Answer in other part of forums :

try :

minimize
    sum (a in 0..2*numJobs) ArcCost[<a, successor&#91;a&#93;>];
