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.
