作者分享了一个N-Body模拟项目，使用环形缓冲区存储天体轨迹。最初使用DrawLine绘制时，绘制10万个点耗时50毫秒，性能瓶颈明显。改用ID2D1PathGeometry后，绘制调用次数减少，性能提升至6毫秒，优化效果显著。总结强调理解Draw Call成本和量化测试的重要性。

本研究提出了一种名为每一次调用都至关重要（ECP）的算法，旨在优化昂贵的非凸黑箱Lipschitz连续函数，尤其是在Lipschitz常数未知的情况下。ECP算法通过聚焦潜在最优区域，显著减少功能评估次数，并在无限评估预算下表现无遗憾，在有限预算下达到极小最大遗憾界限。ECP在多个基准算法中表现优于10种算法，显示出其全球优化的竞争力。
