The initial basic feasible solution (IBFS) is a significant step to achieve the minimal total cost (optimal solution) of the transportation problem.
However, the existing methods of IBFS do not always provide a good feasible solution which can reduce the number of iterations to find the optimal solution.
What is a basic feasible solution?
In the theory of linear programming, a basic feasible solution (BFS) is a solution with a minimal set of non-zero variables.
Geometrically, each BFS corresponds to a vertex of the polyhedron of feasible solutions.
If there exists an optimal solution, then there exists an optimal BFS.
How do you tell if a solution is a basic feasible 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.
What does it mean when solutions are adjacent?
Two basic solutions are adjacent if and only if they can be obtained from two adjacent bases (proof is homework).
