Examples of org.drools.planner.core.Solver.solve()

org.drools.planner.core.Solver.solve()
Solves the planning problem. It can take minutes, even hours or days before this method returns, depending on the termination configuration. To terminate a {@link Solver} early, call {@link #terminateEarly()}. @see #terminateEarly()

                solverBenchmark.getSolverConfig().setTerminationConfig(tmpTerminationConfig);
                Solver solver = solverBenchmark.getSolverConfig().buildSolver();
                File unsolvedSolutionFile = result.getUnsolvedSolutionFile();
                Solution unsolvedSolution = readUnsolvedSolution(xStream, unsolvedSolutionFile);
                solver.setPlanningProblem(unsolvedSolution);
                solver.solve();
                solverBenchmark.getSolverConfig().setTerminationConfig(originalTerminationConfig);
                long timeSpend = System.currentTimeMillis() - startingTimeMillis;
                timeLeft = warmUpTimeMillisSpendTotal - timeSpend;
            }
