当我尝试使用 Optaplanner 示例应用程序解决它时，结果并不像图片中的结果，而是如下所示: 
从结果来看，项目0(作业1)和项目1(作业7)的设计作业是并行执行的，而设计师资源只有1人。请帮助我，我犯了什么错误？以及如何解决？
谢谢和问候。
最佳答案
我发布这个答案是为了防止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 xml 输入文件(发布在我的问题中)(源代码是从发行版 zip 中导入且完全未经编辑)，它给了我问题帖子中的第一个结果。然后我尝试从发行版 zip 运行 Optaplanner(使用 runExamples.bat)并尝试解析 xml 输入文件，它给了我预期的结果: 
当我深入研究时，发现项目JobSchedulingScoreRules.drl 可能有一个错误。我尝试将分数计算器从scoreDrl更改为incrementalScoreCalculatorClass，现在它给了我预期的结果。我希望 Optaplanner 团队意识到这个问题。
