WebbBefore we can use Phase I of the Simplex method, we need to develop a procedure to impose the complementary slackness condition of eq. (9.70). The condition is satisfied if both Xi and Xn + m + i are not simultaneously basic variables. or, if they are, then one of them must have a zero value (degenerate basic feasible solution).
