"WebbTwo examples are given (one is commented). Each of them consist of a cost vector, a matrix of restrictions and a right sides vector. Moreover, a basic matrix B containing the initial feasible solution and the indexes of that solution (relative to the matrix of restrictions) are also given. This initial solution is called a basic solution. " - Simplex method can have -ve basic matrix

WebbWe shall relax the latter assumption below. In the original simplex method we have a tableau such as one appearing on p. 10 of CCH; in the revised simplex method we have essentially only the inverse of the current basis, the corresponding values of the Xi, and the present value of z.

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).
