How do you find the feasible basic solution?
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.What is basic feasible solution and feasible solution?
Degenerate basic feasible solution: A basic feasible solution where one or more of the basic variables is zero. Discrete Variable: A decision variable that can only take integer values. Feasible Solution: A solution that satisfies all the constraints.What is basic feasible solution theorem?
Definition: A feasible solution solution x is called basic if either x = 0, or the columns of A, corresponding to nonzero components of x in the above linear combination are linearly independent. a basic feasible solution has k = 0,1,,m positive components and sum over them.) Of course, x = 0 only if b = 0.- 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. The objective-function value at (0,0) is 0 and at (1,1) is 7.
