Knowledge Representation

Knowledge Representation. In which we show how to use first-order logic to represent the most important aspects of the real world. This is a treatise of chapter 12 of Russel & Norvig: AIMA (Ed.3) The notation for FOL will be in implicative normal form, which makes the examples executable.
