今天迁移服务器之后原本正常运行的程序报"Temporary failure in name resolution"错误，意思是域名解析失败，但是DNS什么的设置没有问题，其实是主机名解析失败。常见解决方案是在hosts里配置一下即可。

基于NSGA-II的局部寻优算法改进，结合ZDT和DTLZ系列测试函数，含IGD定值退出机制及测试图片展示 - 局部搜索
08-10
内容概要：本文介绍了一种基于NSGA-II改进的局部寻优算法，重点在于引入局部搜索环节来提高多目标优化的效果。文中详细解释了局部搜索的具体实现方法，包括动态调整步长以及在高维情况下的适应性。同时，作者使用了ZDT和DTLZ系列测试函数进行验证，尤其是对ZDT1和DTLZ4进行了深入探讨。此外，还提出了利用IGD（Inverted Generational Distance）作为终止条件的方法，确保算法能够在达到足够好的解之后停止，避免不必要的计算浪费。最终结果显示，在这两个测试函数上，改进后的算法表现出了更好的前沿贴合度和帕累托分布均匀度。 适合人群：从事多目标优化研究的专业人士，尤其是那些希望深入了解NSGA-II改进版本的人。 使用场景及目标：适用于需要解决复杂多目标优化问题的研究项目，旨在提供一种更加高效且精确的解决方案。 其他说明：需要注意的是，在实际应用中，对于更高维度的问题可能需要进一步调整参数设置，如局部搜索步长的衰减速率等。另外，并行计算过程中应注意各子种群独立管理各自的局部搜索状态，以免造成搜索效率下降。
