I see. Thank you for your promptly reply.

I noticed that TAO includes three interior-point methods, they are Mehrotra Predictor-Corrector Method (bqpip), Primal-Dual Interior-Point Method (pdipm) and "ipm", respectively. I'd like to ask what is the interior-point method implemented by "-tao_type ipm", thank you.
