Adaptation in Natural and Artificial Systems | MIT CogNet

Genetics provides us with a canonical example of a complex search through a space of ill-defined possibilities. The basic problem is one of manipulating representations — the chromosomes — so as to search out and generate useful organization — the functional properties of the organism. Rather, the system acts as if it were continually testing a wide variety of combinations of alleles for use as components in the construction of new chromosomes. In terms familiar to geneticists, the process is searching out coadapted sets of alleles. The alleles belonging to a given coadapted set may be distributed over the chromosome, and a given allele may belong to many distinct coadapted sets. The overall effect is one of steadily biasing the generation of chromosomes toward incorporation of combinations components that have proved useful in similar contexts. It can be proved that this adaptive process, though dealing with a population sample of size M, usefully tests and exploits information about far in excess of M 3 M cubed distinct combinations of alleles.

Scientific Research An Academic Publisher. Holland, J. University of Michigan Press, Ann Arbor. ABSTRACT: The subject area of multiobjective optimization deals with the investigation of optimization problems that possess more than one objective function. Usually, there does not exist a single solution that optimizes all functions simultaneously; quite the contrary, we have solution set that is called nondominated set and elements of this set are usually infinite.

  1. Genetic algorithms are playing an increasingly important role in studies of complex adaptive systems, ranging from adaptive agents in economic theory to the use of machine learning techniques in the design of complex devices such as aircraft turbines and integrated circuits.
