Hello,

The BONMIN manual, which lists the available options for bonmin, indicates (see below) that one can select filterSQP for solving the contnious NLP relaxations.

nlp_solver:
 Choice of the solver for local optima of continuous nlp's 
 



The default value for this string option is "Ipopt".



Possible values:


Ipopt: Interior Point OPTimizer
filterSQP: Sequential quadratic programming trust region
algorithm 
However, when I try to do that with the command line

options bonmin_options " bonmin.nlp_solver filterSQP ";

I systematically get an error message. 
Could you indicate me how to proceed to use filterSQP?
Thanks,
Pratim
