are automatically initialized with the methodDesignSpace.initialize_missing_current_values()
.Constructor.
Generate the library dictionary that contains the list of algorithms with their characteristics.
- LIB_COMPUTE_GRAD = True
- OPTIONS_MAP: dict[str, str] = {'max_iter': 'maxiter', 'redundancy removal': 'rr', 'verbose': 'disp'}
The names of the options in GEMSEO mapping to those in the wrapped library.
- REDUNDANCY_REMOVAL = 'redundancy removal'
- REVISED_SIMPLEX = 'REVISED_SIMPLEX'
- descriptions: dict[str, AlgorithmDescription]
The description of the algorithms contained in the library.
- internal_algo_name: str | None
The internal name of the algorithm used currently.
It typically corresponds to the name of the algorithm in the wrapped library if any.
- opt_grammar: JSONGrammar | None
The grammar defining the options of the current algorithm.
- problem: Any | None
The problem to be solved.
