谢谢和问候 我发布这个答案，以防有人遇到与我相同或类似的问题。首先，我使用从eclipse运行的Optaplanner示例运行问题中发布的xml输入文件。源代码是从发行版zip导入并完全未经编辑的，它给出了问题帖子中的第一个结果。 然后，我尝试使用runExamples.bat从发行版zip运行Optaplanner，并尝试解决xml输入文件，它给出了预期的结果：
当我深入挖掘时，发现projectJobSchedulingScoreRules.drl可能有一个bug。我尝试将分数计算器从scoreDrl更改为IncrementalCoreCalculatorClass，现在它给了我预期的结果。我希望Optaplanner团队意识到这一问题。有趣的是，这确实应该有效。为什么不触发硬约束并影响窗口底部的分数？除了输入xml文件之外，您还做过其他编辑吗？尝试从头开始下载OptaPlanner发行版zip，并使用该zip打开输入文件。除了创建新的输入xml文件，我还没有做任何其他编辑。好的，我将从头开始使用OptaPlanner分发zip运行它，并将很快更新到这里的进度。谢谢
