[Help-glpk] MIP termination

[Xin Huang]

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.
