We will start by trying to see if Generalized Resolution is complete in this respect. We will see how constructive proofs can be created using resolution. However, we will find that resolution on its own is not complete either. We will then try and use resolution with refutation as the proof procedure, and we will see that it is indeed complete. Dolphins are not literate.
Some dolphins are intelligent.
Some beings who are intelligent cannot read. We will also talk about how to convert FOL sentences into Normal clauses. Move negations inside atomic sentences. Standardize variable names. Move universal quantifiers to the outside.
