I have implemented Dijkstra's algorithm for my research on an Economic model, using Python. In my research I am investigating two functions and the differences between them. Every functions takes as input two parameters: F (a,b) and Z (a,b). Every cell of the matrix is defined as: M [ a] [ b] = F ( a, b) − Z ( a, b) .
