  1. Prolog programming

    1. Briefly explain the concept of memoization, and its relation to the predicates assert and asserta.

      Solution: Memoization is the process of noting down the results of complicated computations or inferences that might be needed again later, so that it is not necessary to re-compute them if they are needed. In Prolog this can be done by asserting the fact that has been computed. It is often the case that it is necessary to use asserta in order to ensure that the asserted result is accessed before the rule that would be used if the asserted result were not available.
