Dear Clp mailing list,
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?)
Thanks very much!
Sincerely,
Stephanie Jakus
