Prologis, Inc. is a real estate investment trust headquartered in San Francisco, California that invests in logistics facilities. [5] The company was formed through the merger of AMB Property Corporation and Prologis in June 2011, which made Prologis the largest industrial real estate company in the world.
Prolog syntax and semantics. The syntax and semantics of Prolog, a programming language, are the sets of rules that define how a Prolog program is written and how it is interpreted, respectively. The rules are laid out in ISO standard ISO/IEC 13211 [1] although there are differences in the Prolog implementations .
Cut (logic programming) The cut, in Prolog, is a goal, written as !, which always succeeds but cannot be backtracked. Cuts can prevent unwanted backtracking, which could add unwanted solutions and/or space/time overhead to a query. The cut should be used sparingly.
Prolog is a logic programming language that has its origins in artificial intelligence, automated theorem proving and computational linguistics.. Prolog has its roots in first-order logic, a formal logic, and unlike many other programming languages, Prolog is intended primarily as a declarative programming language: the program is a set of facts and rules, which define relations.
The following Comparison of Prolog implementations provides a reference for the relative feature sets and performance of different implementations of the Prolog computer programming language. A comprehensive discussion of the most significant Prolog systems is presented in an article published in the 50-years of Prolog anniversary issue of the ...

Warren Abstract Machine. In 1983, David H. D. Warren designed an abstract machine for the execution of Prolog consisting of a memory architecture and an instruction set. [1] [2] [3] This design became known as the Warren Abstract Machine (WAM) and has become the de facto standard target for Prolog compilers .
David H. D. Warren is a computer scientist who worked primarily on logic programming and in particular the programming language Prolog in the 1970s and 1980s. Warren wrote the first compiler for Prolog, and the Warren Abstract Machine execution environment for Prolog is named after him. Early life and education
