Webb1 jan. 2000 · To dodge this flaw, in this paper we propose a method using LU decomposition. In contrast to the simplex method, in which an ( m + 1) × ( n + 1) tableau is used, its tableau version handles an ( n − m) × ( n + 1) tableau. In each iteration, its revised version solves a single ( n − m) × ( n − m) system only, compared with the two m × ...
