Reposted-by: emv@msen.com (Edward Vielmetti, MSEN) I know this does NOT strictly belong to any of the groups I am posting it to, but many people are asking information, so I will try to settle the question. 1) the Quine-McCluskey algorithm is a well known algorithm to obtain a minimum sum-of-products (e.g. f = a b' c + a' b + c') representation of a logic function (that is a function with domain {0,1}^n and range {0,1}) from an initial non-optimal sum-of-products representation of it. This finds applications mainly in combinational logic circuit synthesis (but not only there...). 2) the best implementation of this algorithm that I am aware of, is part of the "espresso" logic minimization program. It is available from this university for a nominal fee (there is also anonymous ftp, but that's a bit trickier...). Just send e-mail to erl@janus.berkeley.edu and ask them. Let me know if you have any problem...
