The downhill simplex algorithm was invented by Nelder and Mead [1]. It is a method to find the minimum of a function in more than one independent variable. The method only requires function evaluations, no derivatives. Thus make it a compelling optimization algorithm when analytic derivative formula is difficult to write out.

WebbLet us further emphasize the implications of solving these problems by the simplex method. The opti-mality conditions of the simplex method require that the reduced costs of basic variables be zero. Hence, if xˆ1 > 0, then c1 =6 −1 2 yˆ1 − ˆy2 =0; if xˆ3 > 0, then c3 =13 − ˆy1 −4yˆ2 =0.
