Hello all, I have a very naive question about advisors and the way to implement them. I have a propagator which is very costly and if some condition holds then I don't need to execute it. I am trying to implement this by using advisors: the advisor detects if the condition holds and then returns ES_FIX to avoid propagation. After trying to implement that with not success, I end up by writing a propagator with an advisor that actually prevents the propagator to be executed. This is, a propagator that does nothing because its advisor always return ES_FIX.
The code is attached to this mail but I cannot get the intended behavior, instead, the propagator is executed at every computation space during the search and not only once as I expected. Obviously I am doing something wrong or simply is a misunderstood on what an advisor can do. Any help is very welcome. Thanks in advance, Gustavo
