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 formulas in a …

Jun 19, 2022 · Why should unification in first order logic be limited to unification of first order terms? In first order logic, when unification is defined as a equation, it does not consider unification of formula …

Jan 3, 2022 · I haven't though this through, but I think the answer is yes, but that the unification algorithm may not terminate, and that determining if it terminates for a particular case is as difficult as …

Oct 28, 2020 · 1 In first-order unification, which you seem to be discussing, that is possible assuming X and Z are variables and a is a constant. I'd suggest you check carefully assumptions about …

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 expression of the pair will have P P as …

Feb 17, 2016 · Resolution and unification are important in logic programming if you want to understand how the inference engine works.

Unification of isomorphism theorems and similar algebraic lemmas is one of the main aims of Borceux-Bourn, Mal'cev, protomodular, homological and semi-abelian categories, maybe it contains some of …

Nov 22, 2013 · The most general is $\phi\ x \mapsto y$, since $\psi$ factors though $\phi$ with $\Phi\ y \mapsto c$ (or equivalently $\phi\ y \mapsto x$ and $\Phi\ x \mapsto c$). The usual simple unification …

The unification works by reducing associative functions such as max (a,max (b,c)) onto a varydic and canonical form max (a,b,c) and then performing the pattern matching onto this canonical forms, so all …
