AMPL: A Modeling Language for Mathematical Programming

FILTER Directives for AMPL

To set these directives, assign a string specifying their values to the AMPL option filter_options. For example:
     ampl: option filter_options 'eps=1e-6 rho=100';


eps       Tolerance for solver (default 1E-6)
infty     A large number (default 1E20)
iprint    Print level (silent=0 <= iprint <= 3=verbose)
mxlws     INTEGER workspace length
mxws      REAL workspace length
objno     Objective number: 1 = first, 0 = none
rho       Initial trust region size (default = 10.0)
tt        Parameter for upper bound on filter
ubd       Parameter for upper bound on filter
