About prolog ? History ? Symbolic Programming Language ? Logic Programming Language ? Declarative Programming Language. Prolog Program ? A Prolog program is defined by a set of Predicates ? Each Predicate has a unique Functor and Arity parent(Parent, Child) a predicate whose functor is “parent” with arity 2.
Term A Term is either: Atomic, Variable, or Compound ? Atomic terms can be either atoms or numbers Atoms can be a sequence of alphanumeric (including ‘_’) characters starting with a lower case letter, or a sequence of any characters embedded in single quote marks ? Variables start with a capital letter or _ character Variables that occur with the same name in the same clause represent the same variable, except for “_” ( The anonymous variable, which always represents a unique variable ). 1 Prolog Programming for Artificial Intelligence Three edition 2001 Ivan Bratko Addision Wesley.

Purpose of This Chapter To implement a stored program computer which can execute a set of instructions. Machine Instruction Characteristics Machine Instructions- are instructions executed by the processor. To satisfy a goal means to demonstrate that the goal is true, assuming that the relations in the program is true.

So our program -facts and rules we defined- would be axioms, and the user ’ s question is the conjectured theorem.
