I have a relatively simple question. How do I have OptaPlanner use my own initialized solution as a starting point instead of having a construction heuristic create one? Does this have to be done with a custom SolverPhase? A little more detail on what I'm trying to do: I am scheduling a series of classes and related activities on a calendar. Let's say I have some class BA101 that occurs several times a week (these classes are immovable entities). There are homeworks, exams etc. associated with these classes which I need to schedule. E.g. on Feb 1st, a homework might be due, or on Mar 1st, there might be an exam. So I need to schedule time to do the homework or time to study for the exam. My initial solution for this would be very simple: I would schedule the homework/study time at the same time of the class itself, and let optaplanner move it around till it meets my hard & soft constraints. However, when I tried to do that (i.e. give my homework/study tasks an actual start time instead of just leaving the start time as null), OptaPlanner fell right through without actually making any moves to find the best score. How do I do this? This is my config at the moment, pretty basic (tried this with & without the construction heuristic; same result): <?xml version="1.0" encoding="UTF-8"?> <solver> <solutionClass>com.copilot.optaplanner.domain.ActivityScheduler</solutionClass> <planningEntityClass>com.copilot.optaplanner.domain.Activity</planningEntityClass> <scoreDirectorFactory> <scoreDefinitionType>HARD_SOFT</scoreDefinitionType> <simpleScoreCalculatorClass>com.copilot.optaplanner.solver.score.ActivitySchedulingSimpleScoreCalculator</simpleScoreCalculatorClass> </scoreDirectorFactory> <termination> <maximumSecondsSpend>10</maximumSecondsSpend> </termination> <constructionHeuristic> <constructionHeuristicType>FIRST_FIT</constructionHeuristicType> </constructionHeuristic> <localSearch> <acceptor> <entityTabuSize>7</entityTabuSize> </acceptor> <forager> <acceptedCountLimit>1000</acceptedCountLimit> </forager> </localSearch> </solver> Thanks for any assistance. -- View this message in context: http://drools.46999.n3.nabble.com/Starting-optaplanner-with-your-own-init...
