Solution Goal |
INDEX PREVIOUS NEXT |
A solution goal is a goal that injects a solution, such as a solution supplied by you or a solution found by ILOG CPLEX during the search.
For example, here is a sample in the C++ API which injects a solution at the beginning of branch & bound and then uses a branching goal:
if (getNnodes() == 0) goal = AndGoal(OrGoal(SolutionGoal(goalvar,startVals), AndGoal(MyBranchGoal(getEnv(), var), goal)), goal); else goal = AndGoal(MyBranchGoal(getEnv(), var), goal); return goal; |
For more about this kind of special goal, see Injecting Heuristic Solutions.
