A real multi-parent tri-hybrid evolutionary optimization method with applications in overlapping signal resolution

A real-coded multi-parent tri-hybrid evolutionary algorithm (EA) for problem optimization is presented. The hybrid EA algorithm combines the features of simplex, stochastic relaxation and multi-parent EA reproduction in a model that encourages competition among the best individual solutions front various operations. Its strength has been evaluated using standard test functions and shown to do better than other methods. The algorithm´s ability to handle noise is evident when applied to experiments involving resolution of overlapping Wind Profiler data Results obtained using ram data closely matched those obtained with data preprocessed by a low pass FFT filter. Resolution of low-speed wind and clutter signals in various degrees of overlap is made possible, thereby allowing the determination of wind velocity and variance to be executed with ease
