[petsc-users] An issue of Interior-Point Methods in TAO

[Barry Smith]

  It looks like it was started as a general framework for interior point methods but never finished? 

  There is a note on its manual page "This algorithm is more of a place-holder for future constrained optimization algorithms and should not yet be used for large problems or production code."

   You are welcome to look at the source code and play with it but you should consider it unfinished and unsupported.

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.
