This function creates and returns a node evaluator that implements limited interleaved depth-first search in a Concert Technology model. (The function IloDFSEvaluator implements conventional depth-first search.)

The parameter max is the maximum depth where this evaluator is active. Below this depth, it acts as a depth-first search evaluator.

This function returns an instance of IloNodeEvaluator for use with the member functions IloSolver::startNewSearch and IloSolver::solve. An instance of IloSolver extracts the node evaluator that it returns as an instance of IlcNodeEvaluator for use during a Solver search.
