On comp.constraints you wrote that you have about 50000 constraints. I don't think that "imposing" them will be performance bottleneck - rather SOLVING them will be. A.L. P.S. Could you synchronize this what you write here and on comp.constraints?... > -----Original Message----- > From: > eclipse-users-bounces+lewando=attglobal.net_at_...2... > [mailto:eclipse-users-bounces+lewando=attglobal.net_at_...29... > p.com] On Behalf Of David Tian > Sent: Saturday, March 22, 2008 5:17 PM > To: ECLiPSe Users List > Subject: [eclipse-users] Speed Up Constraint Imposing Time in ECLiPSe > > > Hi, > > My problem is a data mining problem (a discretization > problem) and I modelled it as a constraint satisfaction > optimization problem (CSOP) > and implemented the CSOP using the ic library of ECLiPSe.
