I assume you are creating objects in GLPK, like say a constraint matrix. Do you rely on Java's garbage collector to dispose of these or do you call glpk's delete function (glp_delete_prob)? I do the latter. I don't recall ever noticing R's garbage collector.
So don't use carrays. I use iajaar or sparse matrix from coin. See: http://www.mail-archive.com/[email protected]/msg02581.html I always think that writing ia[x] = etc; ja[x] = etc; ar[x] = etc; is tedious. GLPK should have an add triplet function. Until then use iajaar. > ----- Original Message ----- > From: Xypron <[email protected]> > To: Nigel Galloway <[email protected]> > Cc: "Eagle, Ken" <[email protected]>, [email protected] > Subject: Re: [Help-glpk] glpk and R (using SWIG) > Date: Wed, 16 Jun 2010 00:36:54 +0200 > > > Hello Nigel, > > the SWIG documentation on > http://www.swig.org/Doc1.3/R.html > says: > > Currently the following features are not implemented or broken: > * Garbage collection of created objects > * C Array wrappings > > Some sort of array wrapping is needed for using GLPK. > > Best regards > > Xypron > > Nigel Galloway wrote: > > The benefits (and drawbacks of SWIG) have been widely discussed. > > Using the swig interface files discussed it is possible to > > produce wrappers for all glpk api in R, and add a few usful > > features. > > > -- _______________________________________________ Surf the Web in a faster, safer and easier way: Download Opera 9 at http://www.opera.com _______________________________________________ Help-glpk mailing list [email protected] http://lists.gnu.org/mailman/listinfo/help-glpk
