Hi everyone,

I'm using CP to solve the partially destructed current solutions in ALNS. The problem is that in some iterations, CP takes very long to solve a satisfaction problem. My question is if I could put a time condition in CP to break if it takes more than a specified time t*? I'd appreciate if you could help me about that.

Hello,

I I understand well you are using CP (thus ILOG Solver and/or Scheduler) in C++ and you are writing your own search. In this context, you can use limits (fail or time limits) thanks to the notion of search limits. For instance:

IloGoal myLimitedGoal = IloLimitSearch(env, myGoal, IloTimeLimit(env, timeLimit));

There is an example in the distribution of ILOG Scheduler (scheduler/examples/src/altlns.cpp).
