Particle swarm optimizer with adaptive tabu and mutation: A unified framework for efficient mutation operators
Yu-Xuan Wang, Qiao-Liang Xiang, Zhen-Dong Zhao
Article No.: 1
DOI: 10.1145/1671948.1671949

Evolutionary Algorithms (EAs) and Swarm Intelligence (SI) are widely used to tackle black-box global optimization problems when no prior knowledge is available. In order to increase search diversity and avoid stagnation in local optima, the...

Structured overlay for heterogeneous environments: Design and evaluation of oscar
Šarūnas Girdzijauskas, Anwitaman Datta, Karl Aberer
Article No.: 2
DOI: 10.1145/1671948.1671950

Recent years have seen advances in building large Internet-scale index structures, generally known as structured overlays. Early structured overlays realized distributed hash tables (DHTs) which are ill suited for anything but exact...

The MACODO middleware for context-driven dynamic agent organizations
Danny Weyns, Robrecht Haesevoets, Alexander Helleboogh, Tom Holvoet, Wouter Joosen
Article No.: 3
DOI: 10.1145/1671948.1671951

One of the major challenges in engineering distributed multiagent systems is the coordination necessary to align the behavior of different agents. Decentralization of control implies a style of coordination in which the agents cooperate as peers...

Cooperation through self-similar social networks
Stuart M. Allen, Gualtiero Colombo, Roger M. Whitaker
Article No.: 4
DOI: 10.1145/1671948.1671952

We address the problem of cooperation in decentralized systems, specifically looking at interactions between independent pairs of peers where mutual exchange of resources (e.g., updating or sharing content) is required. In the absence of any...
