XSB XSB extends the standard functionality of
Prolog (being a descendant of PSB- and SB-Prolog) to include
implementations of OLDT (tabling) and HiLog terms. OLDT
resolution is extremely useful for recursive query
computation, allowing programs to terminate correctly in many
cases where Prolog does not. HiLog supports a type of
higher-order programming in which predicate symbols can be
variable or structured. This allows unification to be
performed on the predicate symbols themselves in addition to
the arguments of the predicates. Of course, Tabling and HiLog
can be used together.
Version 1.2
ports: Sun, Solaris, NeXT, Linux, 386 BSD, IRIX, HP-UX
