Current object-oriented (OO) modelling techniques emphasise the static aspects of data objects. Dynamics in general and collaborations between objects in particular tend to be poorly supported and are often treated separately. A full understanding of...

Presentation / Conference Contribution
Holmes, P., & Barclay, P. J. (1996, July). Functional languages on linear chromosomes. Presented at Genetic Programming 1996, Stanford University

Ayala & Kiger (1984) document a biological phenomenon in which co-adapted genes migrate and naturally cluster together into structures called supergenes. We have begun research into the implications of the supergene effect on the efficiency of evolut... Read More about Functional languages on linear chromosomes.
