Abstract: Metaheuristics inspired from nature have gained increasing attention in recent years. They represent a powerful approach to solve NP-difficult problems. There are many examples of adaptive behaviour in natural multi-agent systems. The most known examples are ant colony behaviour and wasp colony behaviour The bio-inspired Ant Colony Optimization model simulates real ant behaviour to find the minimum length path between the ant nest and the food source. The wasp inspires algorithms are based on the model for the selforganization that takes place within a colony of wasps In a colony of wasps, interactions between members of the colony and the local environment result in dynamic distribution of tasks such as foraging and brood care. In addition, a hierarchical social order among the wasps of the colony is formed . .Self-organization, interactions between members of the colony and the local environment, direct and indirect interactions between individuals are very useful in artificial multiagent systems. Computational analogies of natural systems have served as inspiration for multi-agent optimization and control algorithms. Systems composed of several interacting autonomous agents have a big potential to be used in complex problems solving.
The aim of this lecture is to make a survey of ant and wasp based algorithms and models for solving complex optimization problems. Examples of applications of nature inspired algorithms for modeling multiagent systems in various fields are presented and analysed.
