i am to model the distribution of drug to eight region in Ghana using dynamic programming and Dijkstra algorithm. the model will be dynamic programming and use Dijkstra algorithm matrix to find the shortest rout from the drug storage center.
I mean your problem can be viewed as the Traveling Salesman Problem (TSP) or the Multiple TSP (mTSP). In this problem can be used: dynamic programming and Dijkstra algorithm and a variant of linear programming. Your task involves what is known as the longest path problem (LPP). See my literature sources.
