Hi
I am using the lp_integer function after lp_simplex in order to have integer
solutions.
My problem is that I don't know how can make the difference between the state
when the
solver gives this message :
+ 2008: mip = not found yet <= tree is empty (0; 613)
and that message :
+ 2426: mip = 3.186700000e+04 <= tree is empty 0.0% (0; 429)
What my programme is showing is that in the first case, there is no integer
solution, and
that in the second case, there is an integer solution. But I don't know how to
detect it
with the given functions : lpx_mip_status, lpx_get_status(lp),
lpx_get_prim_stat(lp),
and lpx_get_dual_stat returns the same values in both cases !
