(University College Dublin. School of Computer Science and Informatics, 2011)We present a study of dynamic environments with genetic programming to ascertain if a dynamic environment can speed up evolution when compared to an equivalent static environment. We present an analysis of the types of ...

(Elsevier Science, 2008-04)In recent years, economists have been using socio-economic and socio-demographic characteristics to explain self-reported individual happiness or satisfaction with life. Using Geographical Information Systems (GIS), we ...

(ACM, 2011-07-12)This paper is concerned with the effect of the grammar type on grammatical evolution when evolving in dynamic environments. Both representation and dynamic environments have been recognised as important open issues in the ...

(ACM, 2011-07-12)The lack of study of genetic programming in dynamic environments is recognised as a known issue in the field of genetic programming. This study compares the performance of two forms of genetic programming, grammatical ...

(Massachusetts Institute of Technology, 2009-10)This paper proposes a virtual environment system called a lightweight affordable immersion room (LAIR) that we propose for use in space and financially constrained situations. The LAIR consists of four walls arranged in ...

(Springer, 1996-09)In this paper, we study implementation in “economic environments”. It is shown that there is a dense subset of the set of preference profiles such that given an arbitrary social choice function, f, and e>0, there exists ...

(University College Dublin. School of Computer Science and Informatics, 2011-04-14)In this paper we present a new variant of the ant problem in the dynamic problem domain. This approach presents a functional dynamism to the problem landscape, where by the behaviour of the ant is driven by its ability to ...
