Abstract

Problem preprocessing before insertion into a Bimodal Optical Computer (BOC) for solving Ax X b is shown to be required in some cases and desirable in all cases. With enough preprocessing we can achieve wonderful results (equivalent to inverting A). Unfortunately, this defeats the BOC purpose of fast solution. WE show that there are very simple, computationally-inexpensive preprocessing steps which solve some of the representation and conditioning problems, although no 'optimum' procedure is known.
