Subject: | [Help-glpk] MIP termination |
Date: | Wed, 13 Dec 2006 11:19:25 +0300 |
Hi All: I am wondering whether there is some way to set the mip termination criteria. For example: If abs(yyy #8211; xxx) < epsilon then return where xxx and yyy are defined in the description of lpx_integer (e.g. mip = xxx <rho> yyy gap (ppp; qqq)) I notice that there is a parameter called LPX_K_TOLOBJ. However, when I set it to 1 or 0.9, I get an error message say that the value is invalid. Can someone please help me to understand these? Thank you very much. Xin
