cma.fitness_models.SurrogatePopulation.EvaluationManager

class documentation

class EvaluationManager(object):

Manage incremental evaluation of a population of solutions.

Evaluate solutions, add them to the model and keep track of which solutions were evaluated.

Uses model.add_data_row and model.eval.

Details: for simplicity and avoiding the copy construction, we do not inherit from list. Hence we use self.X instead of self.

Method	`__init__`	all is based on the population (list of solutions) `X`
Method	`__len__`	should replace `len(self.X)` etc, not fully in use yet
Method	`add_eval`	add fitness(self.X[i]), not in use
Method	`eval`	add fitness(self.X[i]) to model data, mainly for internal use
Method	`eval_sequence`	evaluate unevaluated entries of X[idx] until `number` entries are evaluated overall.
Method	`surrogate_values`	return surrogate values of `model_eval` with smart offset.
Instance Variable	`evaluated`	Undocumented
Instance Variable	`fvalues`	Undocumented
Instance Variable	`last_evaluations`	Undocumented
Instance Variable	`X`	Undocumented
Property	`evaluation_fraction`	Undocumented
Property	`evaluations`	Undocumented
Property	`remaining`	number of not yet evaluated solutions

def __init__(self, X): ¶

all is based on the population (list of solutions) X

def __len__(self): ¶

should replace len(self.X) etc, not fully in use yet

def add_eval(self, i, fval): ¶

add fitness(self.X[i]), not in use

def eval(self, i, fitness, model_add): ¶

add fitness(self.X[i]) to model data, mainly for internal use

def eval_sequence(self, number, fitness, model_add, idx=None): ¶

evaluate unevaluated entries of X[idx] until number entries are evaluated overall.

Assumes that sorted(idx) == list(range(len(self.X))).

idx defines the evaluation sequence.

The post condition is self.evaluations == min(number, len(self.X)).

def surrogate_values(self, model_eval, true_values_if_all_available=True, f_offset=None): ¶

return surrogate values of model_eval with smart offset.
