Hello: In order to find the best solution of a problem that I'm working on, I have to branch over an IntVarArray , so I have created a custom branch with an heuristic. (like in the black hole or queens example). And use the BAB engine.
This branching works fine, but it could be improved if the vars that should be unassingned after a basic solution is found are selected in a different way. I mean like a custom backtrack with a function that selects the best var to be reassigned. Is that possible? how ? . thank you. PD: I had deleted a lot of old messages of the list, so I dont know if anyone has asked this before. Sorry if this question has been asked.
