From nzhou@acm.org Wed Mar 28 00:28:57 2007 From: nzhou@acm.org (Neng-Fa Zhou) Date: Tue, 27 Mar 2007 18:28:57 -0500 Subject: [bp-users]News about B-Prolog Message-ID: <003801c770c7$b1a74240$6401a8c0@toshibauser> Dear bp-users subscribers, I am pleased to announce the release of B-Prolog version 7.0beta. The new version adopts a new engine that is on average about 40% faster than the previous version on normal Prolog programs. The new version also demonstrates performance enhancements in code size, compile time, and load time. The beta version is available for Windows and Linux only. I am also pleased to share with you the good news that the B-Prolog CSP solver (running on an alpha version of 7.0) was ranked top in two categories in the Second International Solvers Competition. A total number of 21 solvers from around the world entered the competition and 3425 problem instances were used to evaluate and rank the solvers. The problems were divided into five categories (2-ARY-INT, 2-ARY-EXT, N-ARY-INT, N-ARY-EXT, and GLOBAL) based on the arity (2-ARY, N-ARY, GLOBAL) and format of constraints (extensional tables and intentional relations). The B-Prolog CSP solver was ranked top in N-ARY-INT and GLOBAL. Detailed information about the competition is available at: http://www.cril.univ-artois.fr/CPAI06/ I plan to release the final version of 7.0 in a couple of months. Please let me know if you have any requests or comments. Best regards, Neng-Fa www.probp.com
