- logic: unification of a formula - Mathematics Stack Exchange
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 resolution step (provided resolution is applicable to the formulas), a third formula is generated

- Is it possible to use Unification for lambda calculus?
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 the general halting problem Usually the thing we like about unification algorithms is that they always terminate, because they do structural recursion on the input term
- Use unification and resolution to justify proof
Resolution and unification are important in logic programming if you want to understand how the inference engine works

- logic - Using the unification algorithm to determine whether pairs of . . .
I would like to use the unification algorithm to determine whether or not the following pairs of formulas are unifiable, and if so, find a most general unifier, showing all my working
- Substitution To Find Most General Unifier - Mathematics Stack Exchange
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 algorithm will generate an mgu; basically just pick the simplest unification (unify variables to variables, not to some other constants ground terms)
