In the KMAP shown below, I can think of three different ways to minimize it. How can we determine which is correct? I have listed the minimized equations and why I think each one is acceptable below.
I believe this case is acceptable because it has the fewest number of groups, and the largest possible group.
I believe this case is acceptable because it utilizes the overlap rule and doesn't violate any other rule.
I believe this case is acceptable similar to Case 1.
They all are within the rules, so what makes one more correct than the other?
