Not completely understanding why solver.solve() would only run for 1ms,

isn't a partially initialised starting solution a runtime error and (3) have solver.getBestSolution() throw a "SolutionsNotInitialisedException" an option?

1) It returns null. So you 'll need to do null checks: Solution bestSolution = solver.getBestSolution(); if (bestSolution == null) { // ... do things with bestSolution Score bestScore = bestSolution.getScore(); } 2) It returns the partially initialized solution. So you'll need to do isBestSolutionInitialized checks: Solution bestSolution = solver.getBestSolution(); if (solver.isBestSolutionInitialized()) { // ... do things with bestSolution Score bestScore = bestSolution.getScore(); }

It won't be able to completely initialize the solution in that case. What should solver.getBestSolution() return in that case? null or the partially initialized solution? 1) It returns null.
