| Yap is a high-performance Prolog compiler developed at LIACC, Universidade
do Porto. Its Prolog engine is based on the WAM (Warren Abstract Machine),
with several optimizations for better performance, and achieves performance
comparable or exceeding that of commercial Prolog systems. Yap is largely
compatible with the major Edinburgh Prolog systems, and has been ported to
most 32-bit and 64-bit Unix based platforms. A Windows port is also
available. |
