Citysim

We propose an evolutionary approach for studying the dynamics of interaction of strategic agents that interact in a marketplace. The goal is to learn which agent strategies are most suited by observing the distribution of the agents that survive in the market over extended periods of time. We present experimental results from a simulated market, where multiple service providers compete for customers using different deployment and pricing schemes. The results show that heterogeneous strategies evolve and co-exist in the same market.

The Citysim Model

• Simulation of a society of suppliers of a service and their customers.
• The agents live and interact in a circular monocentric city.

The simulation is based on a supply and demand model,

• where multiple service providers compete for customers, and
• where profitability is the criterion to stay in business.
