Construct an LPP by choosing suitable c, A (a 5 x 7 matrix) and b such that it lookslike
Max Z = cx
Subject to
Ax = b
b ≥ 0 and x ≥ 0
with the conditions that A should have rank 3 and none of the existing variables
are slack variables. What do you observe when M –method and two phase
methods are used in such a case.
