Result object.

Description

S3 object returned by ecr containing the best found parameter setting and value in the single-objective case and the Pareto-front/-set in case of a multi-objective optimization problem. Moreover a set of further information, e.g., reason of termination, the control object etc. are returned.

The single objective result object contains the following fields:

task: The ecr_optimization_task.
best.x: Overall best parameter setting.
best.y: Overall best objective value.
log: Logger object.
last.population: Last population.
last.fitness: Numeric vector of fitness values of the last population.
message: Character string describing the reason of termination.

In case of a solved multi-objective function the result object contains the following fields:

task: The ecr_optimization_task.
log: Logger object.
pareto.idx: Indizes of the non-dominated solutions in the last population.
pareto.front: (n x d) matrix of the approximated non-dominated front where n is the number of non-dominated points and d is the number of objectives.
pareto.set: Matrix of decision space values resulting with objective values given in pareto.front.
last.population: Last population.
message: Character string describing the reason of termination.
