I am trying to write a Goal in Cplex and I have some troubles with the behaviour of FailGoal.
What is going to happen if I return FailGoal(env) when the goal stack of the current node is not empty ?
The stack should be discarded and the node pruned, but it seems that the remaining goals are popped from the stack and executed, and then the node is pruned...
Any explanation ?

Hi,

When FailGoal is used, and the stack is not empty, CPLEX should stop using the remaining goals in the stack and move to the next node, if you think it's not the case, you should send your sample to the ILOG support.

What's the strategy you're trying to implement ? Have you also tried using callbacks ? CPLEX 11 the latest version of CPLEX is also worth a try as it provides large perf improvements : http://www.ilog.com/products/cplex/news/whatsnew.cfm
