OptaPlanner 对数求解器相变

Question

我有一个 OptaPlanner 项目，它有一个分阶段配置的求解器，如下所示:

<?xml version="1.0" encoding="UTF-8"?>
<solver>
    ...
    <!--    SOLVER PHASES CONFIGURATION -->
    <!-- First phase: First Fit Decreasing -->
    <constructionHeuristic>
        <constructionHeuristicType>FIRST_FIT</constructionHeuristicType>
    </constructionHeuristic>
    <!-- Second phase: Tabu Search -->
    <localSearch>
        <localSearchType>TABU_SEARCH</localSearchType>
        <termination>
            <terminationCompositionStyle>OR</terminationCompositionStyle>
            <minutesSpentLimit>2</minutesSpentLimit>
            <unimprovedSecondsSpentLimit>20</unimprovedSecondsSpentLimit>
            <bestScoreLimit>0hard/0medium/0soft</bestScoreLimit>
        </termination>
    </localSearch>
    ...
</solver>

我想记录相位的变化。是否可以？谢谢。
