define feasible solution
What is a feasible solution and a basic solution?
A feasible solution is a solution which satisfies the non negative restrictions (i.e., >=0).
That is all the variables must be either zero or greater than zero (i.e., positive).
A basic feasible solution is a solution which satisfies all the constraints and also the non negativity restrictions.A solution (set of values for the decision variables) for which all of the constraints in the Solver model are satisfied is called a feasible solution.
In some problems, a feasible solution is already known; in others, finding a feasible solution may be the hardest part of the problem.
What is meant by feasible solution?
A feasible solution is a set of values for the decision variables that satisfies all of the constraints in an optimization problem.
The set of all feasible solutions defines the feasible region of the problem.
