Abstract: Mechanism design is a method of designing the rules of the game to achieve desirable outcomes despite agents’ acting in their own self-interest. Mechanisms have traditionally been designed manually. Conitzer and Sandholm introduced the automated mechanism design approach. This approach solves mechanism design as optimization problems and uses linear programming to solve them. In this paper we propose a method for automated mechanism design by using particle swarm optimization algorithm. It yielded several mechanisms for divorce settlement scenario problem better than the public literature.
