Web3.1 The Simplex Method Originally designed by Dantzig [ 9], the simplex algorithm and its variants (see [6]) are largely used to solve LP problems. Basically, from an initial feasible solution, the simplex algorithm tries, at each iteration, to build an improved solution while preserving feasibility until optimality is reached. http://www.iaeng.org/publication/IMECS2014/IMECS2014_pp1209-1213.pdf
