DOE algorithms¶
In this example, we will discover the different functions of the API related to design of experiments.
from __future__ import division, unicode_literals
from gemseo.api import (
configure_logger,
get_algorithm_options_schema,
get_available_doe_algorithms,
)
configure_logger()
Out:
<RootLogger root (INFO)>
Get available DOE algorithms¶
The get_available_doe_algorithms()
function returns the list
of optimization algorithms available in GEMSEO or in external modules
print(get_available_doe_algorithms())
Out:
['CustomDOE', 'DiagonalDOE', 'OT_SOBOL', 'OT_RANDOM', 'OT_HASELGROVE', 'OT_REVERSE_HALTON', 'OT_HALTON', 'OT_FAURE', 'OT_MONTE_CARLO', 'OT_FACTORIAL', 'OT_COMPOSITE', 'OT_AXIAL', 'OT_OPT_LHS', 'OT_LHS', 'OT_LHSC', 'OT_FULLFACT', 'OT_SOBOL_INDICES', 'fullfact', 'ff2n', 'pbdesign', 'bbdesign', 'ccdesign', 'lhs']
Get options schema¶
For a given optimization algorithm, e.g. "DiagonalDOE"
,
we can get the options; e.g.
print(get_algorithm_options_schema("DiagonalDOE"))
Out:
{'$schema': 'http://json-schema.org/draft-04/schema', 'description': 'Diagonal DOE algorithm', 'additionalProperties': False, 'type': 'object', 'properties': {'eval_jac': {'description': 'Whether to evaluate the Jacobian.', 'type': 'boolean'}, 'n_processes': {'minimum': 1, 'description': 'The number of processes.', 'type': 'integer'}, 'wait_time_between_samples': {'minimum': 0, 'type': 'number'}, 'n_samples': {'minimum': 2, 'description': 'The number of samples. The number of samples must be greater than or equal to 2.', 'type': 'integer'}, 'max_time': {'minimum': 0.0, 'description': 'The maximum runtime in seconds. If 0, no maximum runtime is set.', 'type': 'number'}, 'reverse': {'anyOf': [{'items': {'type': 'string', 'minItems': 1}, 'description': 'The dimensions or variables to sample from their upper bounds to their lower bounds. If None, every dimension will be sampled from its lower bound to its upper bound.', 'type': 'null'}, {'description': 'The dimensions or variables to sample from their upper bounds to their lower bounds. If None, every dimension will be sampled from its lower bound to its upper bound.', 'type': 'array', 'items': {'minItems': 1, 'type': 'string'}}]}}}
