1, fish swarm algorithm is a swarm intelligence algorithm based on bionics principle, which simulates the behavior of fish swarming, foraging and avoiding predators in water. It is a global optimization algorithm, which is mainly used to solve complex nonlinear optimization problems.

2. Ant colony algorithm is a probabilistic algorithm for finding the optimal path. It was put forward by MarcoDorigo in his doctoral thesis of 1992, and it was inspired by the behavior of ants looking for paths in the process of finding food.
