Damn it, there are two pieces of information missing... Timeline: we aim at the second quarter of 2012 for Gecode 4.0.0. But today I went through some older emails (written when we discussed what Gecode 3.* should be) and there I wrote that Gecode 4 should be around end of 2009. Okay, still trust me! This time everything is much different ;-) Just kidding.
Then, of course: Is there something that we absolutely must do for our users? Christian -- Christian Schulte, www.ict.kth.se/~cschulte/ -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Christian Schulte Sent: Friday, October 14, 2011 3:03 PM To: [email protected] Subject: [gecode-users] Gecode 4.0.0 Dear all, As this year has already a number of releases of Gecode from the 3.* version series we have decided to slow the pace and prepare for Gecode 4.0.0 as the next major release. This mail is just to assure you that we are not dormant but that it will take longer before the next version appears. If there is the need for a bug fix release we will of course do that in the meantime. Our current plan is to include the following features: - Integrate propagator groups, see here: http://web.it.kth.se/~cschulte/paper.php?id=LagerkvistSchulte:CP:2009 - Integrate lightweight dynamic symmetry breaking, see here: Lightweight Dynamic Symmetry Breaking. C. Mears, M. Garcia de la Banda, B. Demoen, M. Wallace. SymCon'08. LDSB is a dynamic symmetry breaking method designed to handle common symmetries efficiently under any variable and value ordering. - Integrate float variables - Provide modeling layer for float variables - Support for restarts during search and large neighborhood search - Make randomized tie-breaking more flexible - Modeling layer for scheduling constraints - Branching for scheduling problems Some more speculative things that might or might not make it are: - Integrate discrepancy-based search that is not LDS (?) - Half-reification, see here: Thibaut Feydy, Zoltan Somogyi, Peter J. Stuckey: Half Reification and Flattening. CP 2011: 286-301 - Redundancy analysis, see here: http://web.it.kth.se/~cschulte/paper.php?id=SchulteStuckey:PPDP:2008 Best Christian -- Christian Schulte, www.ict.kth.se/~cschulte/ _______________________________________________ Gecode users mailing list [email protected] https://www.gecode.org/mailman/listinfo/gecode-users _______________________________________________ Gecode users mailing list [email protected] https://www.gecode.org/mailman/listinfo/gecode-users
