Degeneracy in transportation problem occurs in two ways: 1. Resolution of Degeneracy During the Initial Stage 2. Degeneracy at Subsequent Interactions. 1. Resolution of Degeneracy During the Initial Stage: To resolve degeneracy, we proceed by allocating a small quantity close to zero to one or more (if needed) unoccupied cells so as to get m + n - 1. The [...]
