[Bonmin] filterSQP

[Andreas Waechter]

Hi Gulay,

The options you can set from AMPL directly (using the "options 
bonmin_options" keyword), are only a subset of the options that Bonmin 
understands - you can always set all available options with the bonmin 
options file.

You can see the list of options that bonmin understands directly from AMPL 
by typing

bonmin -=

or look into the source file

Bonmin/src/Interfaces/Ampl/BonAmplTMINLP.cpp, particularly the

AmplTMINLP::fillAmplOptionList(AmplOptionsList* amplOptList)

method.

Hope this helps,

Andreas
