An Accelerated Simplex Method

KongRuirui QiuRuchen ① ZhouTianhui (School of Information Control,Qingdao University of Science and Technology,Qingdao 266042) (① School of Chemical Engineering,Tianjing University, Tianjing 300072)  
A new modified simplex method can effectively accelerate convergence velocity of iteration. A new expansion direction is added. The "Mapping Simplex Method" is used instead of the "Substitution of Simplex Vertexes". The "Simplex Compression" can be chosen in the calculation. The results show that the modified simplex method allows broader initial values with fast convergence velocity, whose iterations decrease from 50~100 to about 30 times. New method can effectively avoid degeneration and failure in the calculation, and can be successfully used in the engineering optimum and data processing.
