Type 1: Problems for which we can guarantee that a polynomial algorithm exists that can be used to solve them
Type 2: Problems for which we can prove that they cannot be solved by a polynomial algorithm
Type 3: Problems for which we are unable to find a polynomial algorithm to solve them, but we are also unable to prove that a polynomial solution for those problems is impossible to find
Let's look at the various classes of problems: ...
