CVXPY is a Python-embedded modeling language for convex optimization problems. It allows you to express your problem in a natural way that follows the math, rather than in the restrictive standard form required by solvers. For example, the following code solves a least-squares problem where the ...
多目标优化(Multiobjective Optimization Problem, MOP)也叫多目标规划,即同时优化多个目标的规划问题。前面讲的都是单目标规划方法,但是在实际生活中,很多决策往往是多目标决策,如购买商品时,既要保证质量,也要价格合适,如果有赠品就更好了。那么,在企业的生产管理中,既希望利润最大化,也希望成本最小化。 在讲Guro...

多目标最优化(Multiobjective Optimization Problem, MOP)是这么一种问题,在一定约束下,它希望使得多个目标都能达到最优。而多个目标往往是互相影响甚至冲突的。在现实生活中,很多问题都要求多个目标最好,或者是妥协最好。比如买车,要便宜,又要省油,还要快。但是一般来说,多个目标同时达到最优的情况是不存在的。比如...

But for my particular problem, all I had to serialize was a simple but long list and a dictionary; so I can use themarshalmodule without any problems. Rewriting the code to usemarshalinstead ofcPickleget it another boost so the fourth and last result was:0.000445931848. That's less than ...

二次锥优化问题(Second-order cone optimization problem) 这类优化问题,如他的名字一样,因为约束里有二次锥约束。 最基本的3次元的二次锥为 3次元的二次锥 看它长得像什么呢?冰激凌,所以叫它冰激凌锥。别急它还有个更加高大上的名字,叫做洛伦兹锥(Lorentz cone)。锥的种类很多,大家可详细搜索一下。
