Oltean Mihai, A light-based device for solving the Hamiltonian path problem, Unconventional Computing, Springer-Verlag, 2006 (accepted).

In this paper we suggest the use of light for performing useful computations. Namely, we propose a special device which uses light rays for solving the Hamiltonian path problem on a directed graph. The device has a graph-like representation and the light is traversing it following the routes given by the connections between nodes. In each node the rays are uniquely marked so that they can be easily identified. At the destination node we will search only for particular rays that have passed only once through each node. We show that the proposed device can solve small and medium instances of the problem in reasonable time.
 

 

Oltean Mihai, Evolving Evolutionary Algorithms with Patterns, Soft Computing, Springer-Verlag (accepted), 2006

A new model for evolving Evolutionary Algorithms (EAs) is proposed in this paper. The model is based on the Multi Expression Programming (MEP) technique. Each MEP chromosome encodes an evolutionary pattern which is repeatedly used for generating the individuals of a new generation. The evolved pattern is embedded into a standard evolutionary scheme which is used for solving a particular problem. Several evolutionary algorithms for function optimization are evolved by using the considered model. The evolved evolutionary algorithms are compared with a human-designed Genetic Algorithm. Numerical experiments show that the evolved evolutionary algorithms can compete with standard approaches for several well-known benchmarking problems.
 

 

Oltean Mihai, Switchable Glass: A possible medium for Evolvable Hardware, NASA conference on Adaptive Hardware Systems, pp 81-87, IEEE CS Press, 2006.

The possibility of using switchable glass (also called smart windows) technology for Evolvable Hardware tasks is suggested in this paper. Switchable glass technology basically means controlling the transmission of light through windows by using electrical power. By applying a variable voltage to the window we can continuously vary the amount of transmitted light. Three existing technologies are reviewed in this paper: Electrochromic Devices, Suspended Particle Devices and Liquid Crystal Devices. An Evolvable Hardware application for a light-based device is described. The proposed device can be used for solving an entire class of problems, instead of one problem only as in the case of other dedicated hardware.
 

 

Oltean Mihai, Evolving Evolutionary Algorithms using Linear Genetic Programming, Evolutionary Computation, MIT Press, Vol. 13, Issue 3, pp. 387-410, 2005.

A new model for evolving Evolutionary Algorithms is proposed in this paper. The model is based on the Linear Genetic Programming (LGP) technique. Every LGP chromosome encodes an EA which is used for solving a particular problem. Several Evolutionary Algorithms for function optimization, the Traveling Salesman Problem and the Quadratic Assignment Problem are evolved by using the considered model. Numerical experiments show that the evolved Evolutionary Algorithms perform similarly and sometimes even better than standard approaches for several well-known benchmarking problems.

According to the No Free Lunch (NFL) theorems all blackbox algorithms perform equally well when compared over the entire set of optimization problems. An important problem related to NFL is finding a test problem for which a given algorithm is better than another given algorithm. Of high interest is finding a function for which Random Search is better than another standard evolutionary algorithm. In this paper we propose an evolutionary approach for solving this problem: we will evolve test functions for which a given algorithm A is better than another given algorithm B. Two ways for representing the evolved functions are employed: as GP trees and as binary strings. Several numerical experiments involving NFL-style Evolutionary Algorithms for function optimization are performed. The results show the effectiveness of the proposed approach. Several test functions for which Random Search performs better than all other considered algorithms have been evolved.
