Method (PAM) to find initial basic feasible solution for balanced transportation model In this problem we determine optimal shipping patterns between origins or Note: Penalty means the difference between two smallest numbers in a row or

Basic feasible solutions: A basic solution which is nonnegative Bland's rule: An anti-cycling pivot rule where the entering variable is the nonbasic variable with a positive Blending constraint: For a product made from a “blend” of different items, Combinatorial Optimization Problem: A mathematical program where the

In all the examples we have seen until now, there was an “easy” initial basic feasible solution: put the slack variables on the left hand side How- ever, this is not problems with equality constraints in the original model Consider the Negating that we get that the optimal objective function value is 5, as we expected
