Silent mode? #13

Closed gondsm closed 7 years ago

gondsm commented 7 years ago

Hello! I'm running the SARSOP solver in a loop, working with several rewards, etc., for a small performance benchmark I'm developing.

However, every time the solver runs, it outputs something like:

Generating a pomdpx file: model.pomdpx

Loading the model ...
  input file   : model.pomdpx
  loading time : 0.00s 

SARSOP initializing ...
  initialization time : 0.00s

I understand that this is probably the underlying SARSOP software spilling out its diagnostics, but is there a way to suppress these output messages, so they don't mess up my own output buffer?

Thanks!

It's because run is used to call the solver. We can add a silent mode that calls success instead. PRs welcome.

Great, I'll take a look! Thanks!
