<font size="1"><div><font>Dear Clp mailing list,</font></div><div><font>I'm using the Clp executable with the barrier method, and running into problems where the complementarity value gets small and then diverges. I'm wondering if there is an option to change the convergence tolerance value for the complementarity when using the barrier method. (I see the options for tolerance on primal and dual feasibility... but are those enough?)</font></div>
