Mijn Mutation Operator for Aerofoil Design Optimisation

A new mutation operator, called Mijn, capable of operating on a set of adjacent bits in one single step, is introduced. Its features are examined and compared against those of the classical bit{{ip mutation. A simple Evolutionary Algorithm, M{EA, is described which is based only on selection and Mijn. This algorithm is used for the solution of an industrial problem, the Inverse Aerofoil Design optimisation, characterised by high search time to achieve satisfying solutions, and its performance is compared against that ooered by a classical binary Genetic Algorithm. The experiments show for our algorithm a noticeable reduction in the time needed to reach a solution of acceptable quality, thus they prove the eeectiveness of the proposed operator and its superiority to GAs for the problem at hand.
