一句话很难概括 Wiki 上 说的很好了 Semidefinite programming (SDP) is a subfield of convex optimization concerned with the optimization of a linear objective function over the intersection of the cone of positive semidefinite matrices with an affine space。 Boyd那本书有讲

wiki上的解释你要是看不懂的话,建议你还是看看优化的书吧.

一句话概括:SDP 基本上没法 scale。 发发 paper 还成

我不牛。说说体会 1. 可微分convex函数总可以找到全局最优解。SDP的全局最优解不一定能找到。 2. SDP的关键是约束条件以可是任何函数。convex programming的objective function and constraints都要是convex才行。 3. 能用convex programming解的问题都可以用SDP解。凡是convex programming能找到 的解一定不比SDP差。 一句话:尽量用convex programming。实在不行再用SDP。
If I know my case number, is there a way to check the status? How to do it? A lot of thanks.

Only your lawyer can log onto DOL's website to check the status. DOL will send an email to your lawyer's email automatically once the PERM gets approved.
