Locations are generally represented by a pair of indices (row, column) into the above structures. But for the floyd warshall algorithm we need a distance graph. To translate between the graph format and the map data structure, we have a list of cells. Cells are a base 23 representation of the row,column indices (In other words 9 represents row 0, column 9, while 23 represents row 1, column 0, and HQ has a cell value of (23*11)+11).) |
