What is feasible solution and non degenerate solution in transportation problem?

उत्तर
Feasible Solution: A feasible solution to a transportation problem is a set of non-negative values xij (i = 1, 2, … m, j = 1, 2, … n) that satisfies the constraints.
Non-degenerate basic feasible solution: If a basic feasible solution to a transportation problem contains exactly m + n – 1 allocations in independent positions, it is called a Non-degenerate basic feasible solution.
Here m is the number of rows and n is the number of columns in a transportation problem.
