本文介绍了CodeQL在Java中的调用图分析，用户可以通过Callable和Call类识别未被调用的方法。示例查询展示了如何找到未被其他方法调用的可调用对象，并提供了排除特定方法和构造函数的策略，以减少查询结果。同时，文章提到反射调用和JUnit测试方法的特殊情况，强调了识别未使用方法的复杂性。

电子科技大学的论文《Experience Memory Graph》提出了一种通过图匹配范式改进智能体错误恢复的新方法。该方法在训练阶段将成功与失败轨迹转化为有向图，在测试时一次性检索纠正策略，避免了传统反思循环的低效和高成本。实验结果表明，EMG在ALFWorld和ScienceWorld基准上优于现有方法，提升了准确率和效率，适用于小型语言模型。

本文介绍了Git中的commit-graph和pack bitmap机制及其作用。commit-graph用于加速遍历提交历史，记录提交的拓扑和代数编号；pack bitmap则预计算对象的可达性位图，以优化遍历性能。这两者不改变对象库的语义，删除后功能仍然正常，但可能会变慢。建议在本地仓库进行性能对比实验。
