Re: [Help-glpk] GLPK 4.38 for Java under Linux

I already thought of this way of getting rid of a variable. But keeping all the variables in the model, even bounded to 0, won´t slow down the simplex method? (there may be quite a lot of "removed" variables)

Rather than to "physically" remove a basic column from the problem
object with glp_del_cols you can "logically" remove it fixing it at
zero with glp_set_col_bnds(..., GLP_FX, 0, 0). In this case the basis
remains valid.
