Hello GLPK list Two recent posts to this list discussed the use of wrappers to the GLPK API (application programming interface).
Barry Roundree's posting (appended) mentioned a GLPK "wrapper library". And Balazs DEZSO posted on a similar topic (Date: Tue, 15 May 2007 20:22:02 +0400, Message-ID: <[EMAIL PROTECTED]>, Subject: Re: [Help-glpk] lpx_integer) in relation to interpreting GLPK returns. I also needed to write a semi-intelligent C++ wrapper to interface with GLPK. I called it SiGlpk -- solver interface to GLPK. Some to this code may need to be simplified in light of the changes scheduled for 4.17 GLPK. Moreover the code is currently undergoing testing and refinement (largely motivated by a change in platform). SiGlpk uses the same GPL (GNU general public license) as GLPK and is thus fully compatible with GLPK. I will make this code available to this list when stable, perhaps three months time. If anyone else is doing similar work, perhaps they could post back to this list with some details. with best wishes Robbie --- > Message: 1 > Date: Wed, 23 May 2007 15:37:45 -0400 > From: Barry Rountree <[EMAIL PROTECTED]> > Subject: Re: [Help-glpk] out-of-memory workarounds [Fixed] > To: [email protected] > Message-ID: <[EMAIL PROTECTED]> > Content-Type: text/plain; charset="iso-8859-1" > > Replying to my own email: > > I've added a table lookup that converts my > handy-but-VERY-sparse indexing into a much more > compact form.
