ecr_result: Result object.
In jakobbossek/ecr: Evolutionary Computing in R

Description

S3 object returned by doTheEvolution 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:

final.opt.state: The last optimization state.
task: The ecr_optimization_task.
control: The ecr_control object passed to doTheEvolution.
best.param: Overall best parameter setting.
best.value: Overall best objective value.
opt.path: Optimization path OptPath.
last.population: Last population.
population.storage: Named list of populations stored during the process.
message: Character string describing the reason of termination.

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

final.opt.state: The last optimization state.
task: The ecr_optimization_task.
control: The ecr_control object passed to doTheEvolution.
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.
population.storage: Named list of populations stored during the process.
message: Character string describing the reason of termination.
