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 …

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 …

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 …

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 …

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 …

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

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 …

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 …

Nov 26, 2023 · The (initial) purpose of atomic measures such as the Dirac one is the unification of discrete summation and continuous integration as a single object for probability theory.
