First-Order Logic (FOL or FOPC) Syntax
The unification algorithm is simple. if both sides are constants (numbers, strings, atoms, etc.) the result unifies it it is the same one; if one side is ...

Such systems require a formal language to describe the real world; and the real world has things in it. For this rea son, classical AI adopted first-order logic—the ...
The unification problem is decidable in first order logic. It has been independently investigated by J. R. Guard (1964) under the name of. "matching" and J. A. ...
