经典最优化方法最优化方法是一门古老而又年青的学科。这门学科的源头可以追溯到17世纪法国数学家拉格朗日关于一个函数在一组等式约束条件下的极值问题（求解多元函数极值的Lagrange乘数法）。-Classical optimization methods optimization method is an old and young subjects. The source of this discipline can be traced back to 17th century French mathematician Lagrange function in a group of about a condition of extreme equality constrained problem (solving the extreme value of the Lagrange multiplier Function method).
