Petrick’s MethodAn Example
P = P1 P4 P5 + P1 P2 P5 P6 + P2 P3 P4 P5 + P1 P4 P3 P6 + P2 P3 P6
This expression says that to cover all the minterms
we must include the terms in line P1 and line P4 and
line P5, or we must include line P1, and line P2, and
line P5, and line P6, or …
Considering that all the terms P1, P2, … have the same
cost, how many minimal forms the function has?
