But I have the following observations. 1/ During configuration, I guess this statement is what was sought: checking whether to use zlib data compression library... no 2/ The 'wood1p.sif' file needed the blank lines removed before GLPSOL would process the file. That could be a bit fussy -- at the very least, a message stating that blank lines are causing problems would be helpful. 3/ Your test 2 gave a small difference on output -- leading and trailing zeros were added or the decimal points were omitted as required (I much prefer the GLPK formatting), for example (GLPK second): RHS TOTALL 1. BMIN01 .85 RHS1 TOTALL 1 BMIN01 0.85 4/ Finally, and of more concern, GLPSOL ate my file when I incorrectly issued these commands: $ ls oops.sif.gz $ ./glpsol --check oops.sif --wmps oops.sif.gz $ ls <nothing!> GLPSOL should really not do that! always happy to do testing Robbie --- Robbie Morrison PhD student -- policy-oriented energy system simulation Institute for Energy Engineering (IET) Technical University of Berlin (TU-Berlin), Germany University email (redirected) : [email protected] Webmail (preferred) : [email protected] [from Webmail client] _______________________________________________ Help-glpk mailing list [email protected] https://lists.gnu.org/mailman/listinfo/help-glpk
