Understanding of Ant colony code

01 January 1970 0 9K Report

Dear Sir,

I have a python code for ACO

Code goes like:

self._start_travel(start_node) : Initialize all the ants to start_node & initialize pheromone to 1 self._find_edge(start_node, end_node) : for all the ants Select edges till end node reach self._finish_travel(end_node): Evaporate pheromone.

Here the Evaporation of Pheromone done once by the ants which reach to the destination. So I am not able to understand where the Pheromone deposition works?

Any one have idea,How actually implement ACO in Python for the Given directed graph?
