Ed. M. Akg��l, Alberto Colorni, Marco Dorigo, Vittorio Maniezzo, Politecnico Di Milano

this paper we present the results of a research relative to the ascertainment of limits and potentialities of genetic algorithms ([Dorigo, 1989], [DeJong-Spears, 1989], [Goldberg, 1989]) in...

Teamwork in Self-Organised Robot Colonies

Nouyan, Shervin, Groß, Roderich, Bonani, Michael, Mondada, F., Dorigo, Marco

Swarm robotics draws inspiration from decentralised, self-organising biological systems in general and from the collective behaviour of social insects in particular. In social insect colonies, many...

ACO Algorithms for the Quadratic Assignment Problem

Thomas Stützle, Marco Dorigo

Introduction The quadratic assignment problem (QAP) is an important problem in theory and practice. Many practical problems like backboard wiring [33], campus and hospital layout [8, 14], typewriter...

New Perspectives About Default Hierarchies Formation In Learning Classifier Systems

Marco Dorigo

this paper we present some results of research in default hierarchies formation. A default hierarchy is a set of rules that models a set of environmental states in which some default rules cover most...

Machine Learning For Autonomous Robotic Agents

Andrea Bonarini, Giuseppe Borghi, Pierguido V. Caironi, Marco Colombetti, Marco Dorigo, Fabio Marchese, ...

We present some results of our research in the field of Machine Learning applied to robotics problems. In particular we have investigated on: (i) the application of Learning Classifier Systems to the...

Using Transputers To Increase Speed And Flexibility Of Genetics-Based Machine Learning Systems

Marco Dorigo

We implemented a distributed environment for machine learning experimentation on a transputer network. The system can be used by a researcher to build modular and efficient learning systems. The...

Adaptive sample size and importance sampling in estimation-based local search for the probabilistic traveling salesman problem

Balaprakash, Prasanna, Birattari, Mauro, Stützle, Thomas, Dorigo, Marco

The probabilistic traveling salesman problem is a paradigmatic example of a stochastic combinatorial optimization problem. For this problem, recently an estimation-based local search algorithm using...
