[phenixbb] give-up-quick Phaser in Rosetta

[Morten Grøftehauge]

Dear Phenixbb,

I was wondering if there was any way of getting Rosetta to give up easily
and move on to another search model?
Say I have 20 or more equally awful search models. I think there's a
possibility that one of them will knock it out of the park (i.e. TFZ > 8).
But even if I have Phaser set to fast search I will end up with an
exhaustive search because the search models are so bad.

      fast_search_mode= True Run phaser with selection_criteria_rot_value and
                        then if no obvious solution, repeat with cutoff
                        lowered by search_down_percent
search_down_percent= 25 Used if fast_search_mode=True. Run phaser with
                           selection_criteria_rot_value and then if no obvious
                           solution, repeat with cutoff lowered by
search_down_percent


If I set search_down_percent to 75 does this mean that Phaser will give up
easily and move on to the next model? Is this a terrible strategy
CPU-time-wise?
I am of course aware that search_down_percent is much more likely to give
me the right solution for a given model but in this case there are just so
many possible search models.

Cheers,
Morten
