Abstract :
A measure of the minimum cost of a logical network is important in the evaluation of such networks. A hypothesis is investigated which states that the average minimum cost depends on both the number of input variables and the entropy (``entropy´´ in this sense is based on the probability of a ``1´´ in the functions´ truth table) of the function realized. Some experimental results are presented to support the hypothesis.
