...algorithm any easier to understand and has potential problems with numeric overflows. Gustavo Niemeyer [9] points out that using a more Pythonic data structure than tuples, to store information about node distances, increases readability. Two equivalent node structures (one using None, the other using Max) and their use in a suitably modified Dijkstra's shortest path algorithm is given below. class SuperNode: def __init__(self, node, parent, distance, visited): self.node = node ...
