Complex systems are usually affected by various sources of uncertainty, and it is essential to account for mechanisms that ensure the proper management such disturbances. This paper introduces a novel approach solve symbolic regression problems, which combines potential Grammatical Evolution obtain solutions describing search space with context-free grammars, ability Modal Interval Analysis (MI...

Evolution and the brain have done a marvelous job solving many tricky problems in action control, including problems of learning, hierarchical control over serial behavior, continuous recalibration, and fluency in the face of slow feedback. Given that evolution tends to be conservative, it should not be surprising that these solutions are exploited to solve other tricky problems, such as the de...

Grammatical Evolution (GE) is a grammar based GA to generate computer programs which has been shown to be comparable with GP when applied to a diverse array of problems. GE has the distinction that its input is a BNF, which permits it to generate programs in any language, of arbitrary complexity, including loops, multiple line functions etc. Part of the power of GE is that it is closer to natur...
