I am not sure if I understand the first paragraph of your email. The algorithms are shortest/fastest path finders(I call them non-sumo algorithms). Actually the thing I want to do is as follow: -Import map of a city as road network -Make some source and target points based on the map -Run random number of source-target queries between these source and target points and for every query (or in a time interval for example every 20 second) get the current situation of the network (like the travel time of edges because it might have changed due to heavy traffic in some edges) and find the shortest path/fastest using non-sumo algorithms. -calculate the path found (time/distance) by non-sumo algorithms for each source-target query and also average of time-distance for the whole s-t queries during simulation.
