XSB extends Prolog with tabled resolution and HiLog.
The open source XSB implementation includes an interface to the Java programming language.
Features
XSB features tabled resolution and supports the HiLog language (a standard extension of Prolog permitting limited higher-order logic programming). Tabling enables XSB to implement the well-founded semantics and makes it suitable as a deductive database engine.
History
XSB was originally developed at Stony Brook University by David S. Warren, Terrance Swift, and Kostis Sagonas and launched in 1993-4. It was based on the SB-Prolog language that was also developed at Stony Brook University in 1986,[1][2] and it was the first implementation of tabled resolution.
Syntax
XSB supports several standard programming language data types such as Integers, Floating Point numbers, and Atoms.
Integers in XSB can be interpreted in multiple bases. By default integers are interpreted in base 10 but can be interpreted in a range of bases from 2 to 36.[3]
Atoms are similar to Strings. They are a sequence of characters.
