Webbsolutions. the simplex method starts at the origin (point A) where x1=0 and x2=0. At this starting point, the value of the objective function, z, is zero, and the logical question is whether an increase in nonbasic x1 and/or x2 above their current zero values can improve (increase) the value of z. We answer this question by investigating Webb13 apr. 2016 · In the simplex method, you are really moving along a boundary that consists of connected line segments, each corresponding to a different (linear) constraint.
