Hi, I have a problem whose bounds are values which need (really) a lot of precision. Much more than double can offer. I've handled these values so far with GNU MPFR, which can AFAIK convert to GNU GMP types which are (?) internally used by GLPK if it's built with support for that.
Looking through the source I see that the functions to set bounds as well as the structures (for example struct GLPROW) use double. Thus I guess I'd need to change that at least ... Given I have no knowledge (yet?) about the internal complexities of GLPK ... how hard do you estimate it to be to change GLPK to allow bounds set from GMP numbers? Best regards, Daniel
