This paper studies the phase balancing of a two and three-agent system where the agents are coupled through heterogeneous controller gains. Balancing refers to the situation in which the movement of agents causes the position of their centroid to become stationary. We generalize existing results and show that by using heterogeneous controller gains, the velocity directions of the agents in bala...

In this paper, some privacy-preserving features for distributed subgradient optimization algorithms are considered. Most of the existing distributed algorithms focus mainly on the algorithm design and convergence analysis, but not the protection of agents' privacy. Privacy is becoming an increasingly important issue in applications involving sensitive information. In this paper, we first show t...

Most of researches for conventional simulations were studied focusing on flocks with a single species. While there exist the flocking behaviors with a single species in nature, the flocking behaviors are frequently observed with multi-species. This paper studies on the flocking simulation for heterogeneous agents. In order to simulate the flocks for heterogeneous agents, the conventional method...

This Special Issue consists mostly of the work presented at the Tenth Workshop on Economic Heterogeneous Interacting Agents (WEHIA 2005) hosted by the Centre for Computational Finance and Economic Agents of the University of Essex, UK. The collection reports on advances in an exciting and fast growing subfield of economics, with replication and analysis of markets and other socio-economic envir...

Intelligent agents should be able to communicate with each other using an extensible, expressive language. Agents should have the ability work together in a heterogeneous environment to solve complex goals, while, acting on their own initiative and maintaining autonomy. Current agent communication languages are not expressive enough to facilitate coordination of agents in a heterogeneous system...

We consider an asset-pricing model with wealth dynamics in a market populated by heterogeneous agents. By assuming that all agents belonging to the same group agree to share their wealth whenever an agent joins the group or leaves it , we develop an adaptive model which characterizes the evolution of wealth distribution when agents switch between different trading strategies. Two groups with he...

I study the ex-ante efficient allocation of a set of quality-heterogeneous objects to a number of heterogeneous risk-neutral agents. Agents have independent private values, which represent the maximum cost they are willing to sustain to obtain an object of unitary quality. The designer faces a trade-off between allocative efficiency and cost of screening, because the cost sustained is wasted. T...
