What is an initial basic feasible solution of a transportation problem?

An initial basic feasible solution (IBFS) of a transportation problem is a starting point that satisfies the supply and demand constraints while ensuring that the total transportation costs are minimized. It is typically obtained using methods like the Northwest Corner Rule, Least Cost Method, or Vogel's Approximation Method. The IBFS does not necessarily optimize the cost but provides a feasible allocation of resources that can be further improved through optimization techniques.
