The Unification Algorithm is described at page 84. You have to recall the resolution calculus [page 29] : Resolution is a simple syntactic transformation applied to formulas. From two given …

Dec 9, 2012 · 3 There is no unification in either case, since whatever you substitute for x x (and perhaps a a; you didn't state which symbols are variables to be substituted), the first …

Nov 22, 2013 · The usual simple unification algorithm will generate an mgu; basically just pick the simplest unification (unify variables to variables, not to some other constants/ground terms).

Feb 3, 2020 · My professor asks us to either prove a logical consequence by resolution or disprove it by giving a suitable interpretation. While doing one of the tasks, I encountered a …
