The motifs use a stochastic regular expression language that uses codon-level probabilities within conserved sets (masks). Experiments compared basic genetic programming with Lamarckian evolution, as well as the use of {"}natural{"} probability distributions for masks obtained from the sequence database. It was found that Lamarckian evolution was detrimental to the probability performance of motifs. A comparison of evolved and natural mask probability schemes is inconclusive, since these strategies produce incompatible characterisations of motif fitness as used by the genetic programming system.}, citeseer-references = {oai:CiteSeerPSU:42914; oai:CiteSeerPSU:212791; oai:CiteSeerPSU:215947; oai:CiteSeerPSU:331862; oai:CiteSeerPSU:503937; oai:CiteSeerPSU:506252}, citeseer-isreferencedby = {oai:CiteSeerPSU:79088}, organisation = {The International Association of Science and Technology for Development (IASTED)}, rights = {unrestricted}, oai = {oai:CiteSeerPSU:503706}, language = {en}, keywords = {algorithms, expressions, genetic motif programming, protein regular stochastic } }
