Aiming at the problems of computational complexity’s exponential growth with the size’s increment of the specific problems in automated mechanism design

an improved chaotic ant swarm algorithm is presented.Based on mechanism design

according to constraints of incentive compatibility and individual rationality

models are analyzed for the dominant strategy mechanism and Bayesian—Nash equilibrium mechanism in automated mechanism design

and both of the mechanism models are achieved using the improved algorithm.It is demonstrated that the improved algorithm has achieved good effect on public goods distribution problems.
