PEGASUS - Java-based Protein Prediction Web Service

Distributed Internet application in Java for DNA sequence analysis and protein prediction. This is an enhanced version of an earlier project developed in parallel with the BSc thesis during 1996-1997.

GENESIS: Virtual Environment for Evaluating Multi-Agent Adaptive Models

The GENESIS project is an idea realized by a group of researchers and postgraduate students from Greece, with common interests in artificial intelligence, adaptive agents and distributed systems. Based in the concepts of A-life, the main goal is to create a useful, modular, robust, distributed virtual environment which will be used for the deployment of various kinds of "intelligent" agents. Using a common framework for both environment and agents' basic architecture, different kinds of agents will be deployed dynamically, with the one and common goal of survival through genetic optimization and behavioral adaptation to the environment. Using various control schemes for each agent class, from genetic algorithms, neural networks, fuzzy rule set, even linear optimization, the effectiveness of each method in a competitive environment will be studied in an interactive and illustrative way, observing real-world eco-society attributes like survivability ratios, robustness to harsh environmental conditions, fight-or-flee mechnisms, etc. [download: pdf ]
