State assignment and entropy

A recent paper has presented a method of state assignment based upon the maximisation of true (or false) minterms in the next-state functions. This method has the advantage of very elegant implementation. This letter seeks to interpret these results in the light of the concept of entropy. It is shown that there is some justification for using the maximisation of true (false) minterms for optimal state assignment and some indication is given of the limitations of the method.
