  • What is a basic feasible solution?

    In the theory of linear programming, a basic feasible solution (BFS) is a solution with a minimal set of non-zero variables.
    Geometrically, each BFS corresponds to a corner of the polyhedron of feasible solutions.
    If there exists an optimal solution, then there exists an optimal BFS.

  • What is an example of a feasible solution?

    A pair of specific values for (x1,x2) is said to be a feasible solution if it satisfies all the constraints. (x1,x2) = (0,0) and (x1,x2) = (1,1) are feasible. (x1,x2) = (1,?1) and (x1,x2) = (1,2) are not feasible.

  • How do you find the basic feasible solution example?

    basic solution: For a system of linear equations Ax = b with n variables and m ? n constraints, set n ? m non-basic variables equal to zero and solve the remaining m basic variables. basic feasible solutions (BFS): a basic solution that is feasible.
    That is Ax = b, x ? 0 and x is a basic solution.

  • How do you find the basic feasible solution example?

    Definition 1.
    We say that a constraint ax ? b is active (or binding) at point ¯x if a¯x = b.
    Definition 2.
    A solution in P = {x : Ax ? b} is called basic feasible if it has n linearly independent active constraints.
