Hi,
I have a big Problem.
I want changing my bound. but, after have to print bounds' variable, I
obtain an other bound.
My code is :
>for(int id=0;id<ncol;id++){
> lpx_set_col_bnds(glpkProbPtr,id+1,LPX_LO,0.0,0.0);
>}
...
>for (int id=0;id<ncol;id++){
> lpx_set_col_bnds(glpkProbPtr,id+1,LPX_DB,0.,4.);
>}
>for(int id=0;id<ncol;id++)
>
> cout<<"LB= "<<lpx_get_col_lb(glpkProbPtr,id+1)<<" and UB=
> "<<lpx_get_col_ub(glpkProbPtr,id+1)<<endl;
I obtain:

I obtain:
before
LB= 0 and UB= 4
LB= 0 and UB= 4
LB= 0 and UB= 4
after
LB= 0 and UB= 0
LB= 0 and UB= 0
LB= 0 and UB= 0
Why?
Thanks
