约束问题-Constraints数组 #46

Closed nebula303 closed 1 year ago

nebula303 commented 1 year ago

你好,我最近在做带约束的贝叶斯优化时也遇到了问题,下图显示的是其中两次迭代中,返回的constraints数组 image 按理说,应当每个元素值都小于0吧,但实际好像有几个会大于0,导致了生成的预测结果实际不能采纳,在进行迭代优化时,可以确保每次迭代满足约束条件吗

对于黑盒约束的优化,难以保证优化过程中100%满足约束。目前的算法(EIC)只能尽量推荐符合约束的点,如果要求进一步提升满足约束的概率,需要其他方法。

EIC算法的原理有相关介绍吗?
