![]() ![]() , tn) where p is a predicate symbol and ts are terms. Variable = string that starts with a capital letter.Atom = string that starts with a lower case letter.Atoms, numbers, variables and compounds are terms.Unification with typical Prolog terminology: ![]() It was somewhat challenging to explain unification when using LP terminology i made an attempt. This corresponds to the use of “atom” in classical first order logic.Īm I correct in assuming that (1) is the proper definition for “atom” when talking about Prolog, and that (2) is the proper definition for “atom” when talking about logic programming? I think that a reason for my confusion is that I think of Prolog as an instance of logic programming.ĮDIT ********************************************** , tn), where the ts are terms and p is a predicate symbol. Riguzzi (2018) and Baral and Gelfond (1994), “atoms” are said to be terms with the form p(t1, t2. (2) In texts about logic programming, e.g. Accordingly these are atoms: john, grandparent, etc. Used as name for compound terms, to represent constants or text.”. (1) In Prolog an atom is said to be a “Textual constant. I am somewhat confused about how to use the word “atom” in a paper we are writing. It also describes how these concepts apply to the work that the Department of Energy’s Office of Science conducts as it helps the United States excel in research across the scientific spectrum.I posted this question on the SWI Prolog Discourse forum and got some useful comments, but maybe people here might also have some ideas about this topic. molecule, a group of two or more atoms that form the smallest identifiable unit into which a pure substance can be divided and still retain the composition and chemical properties of that substance.
