Quine-McCluskey type exact ND SOP relation minimization
•Given an ND relation, e.g. the complete flexibility, its i-set is the set of input minterms that can produce output value i.
•For each i-set, generate all its primes, Pi
•Form covering table with
–one column for each pj in Pi for all i
–one row for each minterm in the input space
•Solve minimum covering problem
–Primes chosen from Pk  is the cover for kth i-set.
