What is a basic feasible solution?
- basic feasible solutions (BFS): a basic solution that is feasible. That is Ax = b, x ‚ 0 and x is a basic solution. The feasible corner-point solutions to an LP are basic feasible solutions. The Simplex Method uses the pivot. procedure to move from one BFS to an “adjacent” BFS with an equal or better objective function value.
What is the basic feasible solution for the two-phase simplex algorithm?
- The resulting basic feasible solution can either be used as a starting solution for the two-phase simplex algorithm with the single artifcial variable or the Big-M method. For the two-phase method, we would solve the Phase I problem: (6.30) min x a s:t: Ax+ B
What is a basic feasible solution to a LP?
