我已经从Optaplanner 7.5版迁移到7.10版。迁移时，我看到bulk（Output）不一样。再次运行时，我没有得到相同的输出。您能否分享迁移时我需要考虑的哪些必要步骤？你能帮我吗？
工作时间表也不同。屏幕截图如下：
主要区别在于运行1执行LS 11040，但同时运行2达到LS 11600 plus，并且环境和其他运行参数保持不变。

答案 0 :(得分：0)
仅保证每个步骤索引的可重复性，而不保证时间（尽管它们是相关的）。使用终止时间（例如2分钟）时，无法保证OptaPlanner将占用多少CPU周期获取以及JVM将如何以及何时进行热点优化。在某些情况下，它实际上几乎没有获得CPU周期。在其他情况下，它会变得足够多-在任何情况下，OptaPlanner都会使用所获得的东西，没有浪费的东西。
从步骤索引级别看，两次运行完全相同（所花费的时间除外）：
First run:
11:37:06.194 ...LS step (11039), time spent (119999), score (0hard/-45187medium/-1556640000soft), best score (0hard/-45154medium/-1549560000soft), accepted/selected move count (1/3), picked move (TimeWindowedCustomer-1 {Vehicle-220} <-tailChainSwap-> TimeWindowedCustomer-8 {Vehicle-78}).
Second run:
11:40:25.467 ...LS step (11039), time spent (116004), score (0hard/-45187medium/-1556640000soft), best score (0hard/-45154medium/-1549560000soft), accepted/selected move count (1/3), picked move (TimeWindowedCustomer-1 {Vehicle-220} <-tailChainSwap-> TimeWindowedCustomer-8 {Vehicle-78}).
要在2个结果之间获得完全相同的结果，请使用步进限制终止。
