"hey man, my pathfinding algorithm is really efficient, and i hate that. can you do something about that?" yes. play in turbo mode to make it faster
algorithm used is the genetic algorithm in a nutshell, the genetic algorithm makes a ton of agents / actors, makes em do random things, and the one that does the best will become the champion. the champion reproduces 20 new agents who are slightly mutated. those 20 agents enter the next generation, and the cycle starts again. it's basically survival of the fittest
