Abstract

Abstract

Original mathematical programming is approximated with quadratic programming which is solved by generalized multiplier method. The following approximating approaches are utilized: 1.Talor formula is used to condense the object function into a second order function in logarithmic form. 2.Duffin approximation is applied to condense constraints. At last, a example is testified and shows that this method is simple, feasible and efficient.
