|Subject:||[Help-glpk] Performance of GLPK-4.4 vs. GLPK3.2.3|
|Date:||Mon, 1 Mar 2004 11:57:38 -0500|
Any one has any performance comparisons of GLPK-4.4 vs. its earlier versions, say GLPK-3.2.3 ?
On my test set of 41 problems(ranging from small toy problems up to 600 rows/300,000 columns), I found GLKP-4.4 is usually slower, especially on some more difficult problems. (See attached.) Moreover, it also uses a few more percent of memory.
Any explanations and/or different observations?
