Webb21 okt. 2014 · I've been asked to write down a Matlab program in order to solve LPs using the Revised Simplex Method.. The code I wrote runs without problems with input data although I've realised it doesn't solve the problem properly, as it does not update the inverse of the basis B (the real core idea of the abovementioned method). 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. daughters of charity dublin 15
