Calibration of Neural Networks Using Genetic Algorithms, with Application to Optimal Path Planning

Genetic algorithms (CA's) are used to search the synaptic weight space of artificial neural systems (ANS) for weight vectors that optimize some network performance function. GA's d o not suffer from some of the architectural constraints involved with other techniques and it is straightforward to incorporate terms into the performance function concerning the metastructure of the ANS. Hence GA's offer a remarkably general approach to calibrating ANS. GA's are applied to the problem of calibrating an ANS that finds optimal paths over a given surface. This problem involves training an ANS on a relatively small set of paths and then examining whether the calibrated ANS is able to find good paths between arbitrary start and end points on the surface.
