Influence of the Adaptive Saddle Slope Gradient on the Evolutionary Saddle Crossing Time

Łojek R.

Prace Naukowe Politechniki Warszawskiej. Elektronika

2009

z. 169

129-136

The ability to cross saddles separating adaptive optima is one of the most interesting features of adaptive processes. It is especially promising in the case of multimodal optimization. This contribution deals with the impact of the saddle slope gradient on the time of the saddle crossing. A suitable adaptive landscape with variable saddle parameters is proposed. A simple model of evolution with the real valued traits; proportional selection, normally distributed modifications and without recombination is used.

Adaptive saddle crossings in diverse landscapes

Chorążyczewski A., Galar R.

z. 156

77-85

There is always a question as to how sound are assessments of evolutionary algorithms capabilities based on the tests made in the specific adaptive landscapes. We present some results of numerical experiments concerning the ability of phenotypic evolution to cross saddles between adaptive peaks of different shapes. Asexual reproduction, proportional selection and normally distributed mutations are used. Some related comments on the benchmarking of evolutionary algorithms are also given.
