I'd like to use Z3 to solve problems that are most naturally expressed in terms of atoms (symbols), sets, predicates, and first order logic. For example (in pseudocode): A = {a1, a2, a3, ...} # A i...

I'm looking for an approach, pattern, or built-in feature in Prolog that I can use to return why a set of predicates failed, at least as far as the predicates in the database are concerned. I'm try...

Monadic First Order Logic, where all predicates take exactly one argument, is a known decidable fragment of first order logic. Testing whether a formula is satisfiable in this logic is decidable, a...

While studying description logics (DL), it is very common to read that it is a fragment of first order logics (FOL), but it is hard to read something explicitely on what is excluded from DL which i...

I have been so confused lately regarding difference between predicate and function in first order logic. My understanding so far is, Predicate is to show a comparison or showing a relation betwee...

Good morning, I want to understand how can I describe something using the first order logic. For example I want to describe what is a film (an entity) and what is an attribute (for example actor: ...

I've been using the following data structure for the representation of propositional logic in Haskell: data Prop = Pred String | Not Prop | And Prop Prop | Or Prop Prop | Impl Prop Prop | E...

Is there any software around that using the Fitch format (used in Language, Proof and Logic), allows one to put a specific set of premises and goals and have it show us the full list of steps...

I've starting looking at the Mercury language, which seems very interesting. I'm a new to logic programming, but pretty experienced with functional programming in Scala and Haskell. One thing I've ...

Can you tell me what is the difference between Propositional logic and First Order logic.This is one my my exam question in AI can you help me to do that

I'm reading a tutorial on Coq. It constructs a bool type as follows: Coq < Inductive bool : Set := true | false. bool is defined bool_rect is defined bool_ind is defined bool_rec is defined T...

I'm learning First Order Logic at the moment. I'm looking at this example: Some dogs bark ∃x (dog(X) Λ bark(x)) All dogs have four legs ∀x (dog(x) -> have_four_legs(x)) My question is: is ...
