To set these directives, assign a string specifying their values to the AMPL option minlp_options
. For example:
ampl: option minlp_options 'eps=1.0e-6 rho=100';
Directives:
eps NLP Optimality tolerance for SQP solver (default 1E-6) infty A large number (default 1E20) iprint Print level (silent=0 <= iprint <= 3=verbose) kmax Dimension of null-space (SQP solver bqpd) maxiter Maximum number of iterations per node for SQP solver miopttol Tolerance (absolute error) for MINLP solver (default 1E-4) mxlws INTEGER workspace length mxws REAL workspace length objno Objective number: 1 = first, 0 = none outlev Print level (0=silent, 3=verbose) plconpri Priority for constraint piecewise-linear terms plobjpr Priority for objective piecewise-linear terms rho Initial trust region radius for SQP solver (default = 10.0) stackmax Maximum size of stack for branch-and-bound (default 5000) timing Whether to time evaluations (1 = yes) tt Parameter for upper bound on filter (SQP solver) ubd Parameter for upper bound on filter (SQP solver)
