CADETProcess.optimization.COBYLA#
- class CADETProcess.optimization.COBYLA(rhobeg, tol, maxiter, disp, catol, f_tol, cv_tol, n_max_evals, n_max_iter, finite_diff_rel_step, jac, progress_frequency, x_tol, similarity_tol, parallelization_backend)[source]#
Wrapper for the COBYLA optimization method from the scipy optimization suite.
It defines the solver options in the ‘options’ variable as a dictionary.
- Supports:
Linear constraints
Linear equality constraints
Nonlinear constraints
- Parameters:
- rhobegfloat, default 1
Reasonable initial changes to the variables.
- tolfloat, default 0.0002
Final accuracy in the optimization (not precisely guaranteed). This is a lower bound on the size of the trust region.
- dispbool, default False
Set to True to print convergence messages. If False, verbosity is ignored and set to 0.
- maxiterint, default 10000
Maximum number of function evaluations.
- catolfloat, default 2e-4
Absolute tolerance for constraint violations.
