Abstract : It is difficult to find good mathematical models for many natural problems such as pattern recognition. Not only does this difficulty preclude finding good solutions for these problems, but it also precludes estimating their complexity using the standard tools of the theory oc computational complexity (Traub, 1985). Part of the difficulty can be traced to symptoms such as ill-definition, fuzziness, and inexactness. However, the difficulty of modeling these problems may be inherent in some cases. Keywords: Photorefractive crystals; Adaptive optical networks; Connectivity; Entropy; Holograms.
