Abstract EN

A novel global optimization method, based on the combination of genetic algorithm (GA) and generalized pattern search (PS) algorithm, is proposed to find global minimal points more effectively and rapidly.

The idea lies in the facts that GA tends to be quite good at finding generally good global solutions, but quite inefficient in finding the last few mutations for the absolute optimum, and that PS is quite efficient in finding absolute optimum in a limited region.

The novel algorithm, named as genetic pattern search (GPS), employs the GA as the search method at every step of PS.

Experiments on five different classical benchmark functions (consisting of Hump, Powell, Rosenbrock, Schaffer, and Woods) demonstrate that the proposed GPS is superior to improved GA and improved PS with respect to success rate.

We applied the GPS to the classification of normal and abnormal structural brain MRI images.

The results indicate that GPS exceeds BP, MBP, IGA, and IPS in terms of classification accuracy.

This suggests that GPS is an effective and viable global optimization method and can be applied to brain MRI classification.
