What is a feasible basis if a linear program satisfies non-negativity constraints?
If the unique solution of satisfies the non-negativity constraints , then B is called a feasible basis . 5. If a linear program has an optimal solution (i.e., it has a feasible solution, and the set of feasible solutions is bounded), then it has an optimal BFS.
How do you find a basic feasible solution?
In general, given a canonical form for any linear program, a basic feasible solution is given by setting the variable isolated in constraint j, called the jth basic-variable, equal to the righthand side of the jth constraint and by setting the remaining variables, called nonbasic, all to zero.
