Abstract class to use for DOE library link See DriverLib

Constructor Abstract class

DESIGN_ALGO_NAME = 'Design algorithm'

EVAL_JAC = 'eval_jac'

MIN_DIMS = 'min_dims'

N_PROCESSES = 'n_processes'

N_SAMPLES = 'n_samples'

PHIP_CRITERIA = 'phi^p'

SAMPLES_TAG = 'samples'

WAIT_TIME_BETWEEN_SAMPLES = 'wait_time_between_samples'

static compute_phip_criteria(samples)

Compute the phi^p criteria (see Morris & Mitchell, Exploratory designs for computational experiments, 1995)

Parameters

samples – design variables list

evaluate_samples(eval_jac=False, n_processes=1, wait_time_between_samples=0)

Evaluates all functions of optimization problem at the samples

Parameters

eval_jac – if True, the jacobian is also evaluated (Default value = False)

export_samples(doe_output_file)

Export samples generated by DOE library to a csv file

Parameters

doe_output_file (string) – export file name

static is_algorithm_suited(algo_dict, problem)

Checks if the algorithm is suited to the problem according to its algo dict

Parameters

• algo_dict – the algorithm characteristics

• problem – the opt_problem to be solved
