vast array of problems with modest effort. A linear programming problem is charac- terized, as the name implies, by linear functions of the unknowns; the objective is linear in the unknowns, and the constraints are linear equalities or linear inequal- ...

非线性优化是应用数学和计算科学领域里的一种常见的优化方法,也是现如今机器学习算法的基石。非线性优化问题(Non-Linear Optimization Problem --- NLP)的一般式为: \begin{align*} & minimize\quad &f(x)\\ & subject \quad to\quad & g(x)_i \leq 0 \quad i = 1,...,l\\ && h(x)_j = 0...
Primal linear programming problem (LPP): P: minimise cx with x>=0 and Ax≥b D: maximise by with y>=0 and ATy≤c 要证明的话也可以用反证法把D的不等式*-1变为>=和minimise -by,此时它的新的Duality依然是P。 一个在解题中比较常用的complementary slackness:如果x is optimal for P and y...
