Test the Dual Simplex Algorithm for solving Linear Programming problems.
Test the Dual Simplex Algorithm for solving Linear Programming problems.
- a
the constraint matrix
- b
the limit/RHS vector
- c
the cost vector
- def test1(): Unit
Test case 1: Initialize matrix 'a', vectors 'b' and 'c', and optionally the basis 'x_B'.
Test case 1: Initialize matrix 'a', vectors 'b' and 'c', and optionally the basis 'x_B'. For Dual Simplex, matrix 'a' and vector 'c' are not augmented. -------------------------------------------------------------------------- Minimize z = 2x_0 + 3x_1 + 4x_2 Subject to 1x_0 + 2x_1 + 1x_2 >= 3 2x_0 - 1x_1 + 3x_2 >= 4 where z is the objective variable and x is the decision vector. Since constraints are >=, multiply by rows by -1 -------------------------------------------------------------------------- Dual Solution: x = (11/5, 2/5), x_B = (0, 1), f = 28/5
