[Help-glpk] variable fixing in mip solver?

[Shubhashis Ghosh]

Hi,
        I am wondering whether any variable fixing operation has been done 
at the nodes of branch and bound mip solver. Or it's just a normal branch 
and bound framework based on the lp solver. How the branching variables 
are chosen in this implementation?

thanks,
