How many basic solutions are feasible?
The two solutions we get from the simplex method are the only ones that are basic feasible solutions due to the fact that we are limited to two basic variables for the constraints (as you can only have as many basic variables as you have constraints).How do you find the number of basic feasible solutions?
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 many types of feasible solutions are there?
Basic feasible solutions are of twotypes:Degenerate:A basic feasible solution is called degenerate if value of atleast one basic variable is zero. Non-degenerate:A basic feasible solution is called non-degenerate ifvalues all m basic variables are non-zero and positive.- By definition, the maximum number of possible basic solutions for 'm' equations in n unknowns is. ( n m ) = n m ( m ? n )
