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';
Directives:
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
