Home assignment 3 : Margus Martsepp 121843IAPM Experimenting with predicate provers. Advanced Course of Applied Logics ( ITV0081 ) Part A : Warmers Task 1 What is the most general unifier of the following atoms: p(X,f(Y),Z) p(T,T,g(cat)) p(f(dog),S,g(W)) solution: = { X/T, S/T, T/f[Y], Z/g(cat), W/cat, dog/Y } Task 2 List all the binary resolvants of the following two clauses: p(X,f(Y),Z) | p(T,T,g(cat)) | r(X,T) | ~s(Z,T) ~p(f(dog),S,g(W)) | s(big,rat) | ~s(small,hamster) solution sourse: 1st option (1.4-2.2) = { Z/big, T/rat } p(X,f(Y),big) | p(rat,rat,g(cat)) | r(X,rat) ~p(f(dog),S,g(W)) | ~s(small,hamster)
