(description
|
||
|
|
"GNU Prolog is a free Prolog compiler with constraint solving over
|
||
|
|
finite domains developed by Daniel Diaz.
|
||
|
|
|
||
|
|
GNU Prolog accepts Prolog+constraint programs and produces native
|
||
|
|
binaries (like gcc does from a C source). The obtained executable is
|
||
|
|
then stand-alone. The size of this executable can be quite small since
|
||
|
|
GNU Prolog can avoid to link the code of most unused built-in
|
||
|
|
predicates. The performances of GNU Prolog are very
|
||
|
|
encouraging (comparable to commercial systems).
|
||
|
|
|
||
|
|
Beside the native-code compilation, GNU Prolog offers a classical
|
||
|
|
interactive interpreter (top-level) with a debugger.
|
||
|
|
|
||
|
|
The Prolog part conforms to the ISO standard for Prolog with many
|
||
|
|
extensions very useful in practice (e.g., global variables, OS
|
||
|
|
interface, sockets).
|
||
|
|
|
||
|
|
GNU Prolog also includes an efficient constraint solver over finite domains.
|
||
|
|
This opens contraint logic programming to the user combining the power of
|
||
|
|
constraint programming to the declarativity of logic programming.")
