Higher-level interface to launch irace.Source:
Higher-level interface to launch irace.
A data frame with the set of best algorithm configurations found by irace. The data frame has the following columns:
.ID.: Internal id of the candidate configuration.
Parameter names: One column per parameter name in
.PARENT.: Internal id of the parent candidate configuration.
Additionally, this function saves an R data file containing an object called
iraceResults. The path of the file is indicated in
iraceResults object is a list with the following structure:
The scenario R object containing the irace options used for the execution. See
defaultScenariofor more information.
The parameters R object containing the description of the target algorithm parameters. See
The target algorithm configurations generated by irace. This object is a data frame, each row is a candidate configuration, the first column (
.ID.) indicates the internal identifier of the configuration, the following columns correspond to the parameter values, each column named as the parameter name specified in the parameter object. The final column (
.PARENT.) is the identifier of the configuration from which model the actual configuration was sampled.
A list that contains one element per iteration, each element contains the internal identifier of the elite candidate configurations of the corresponding iteration (identifiers correspond to
A vector containing the best candidate configuration internal identifier of each iteration. The best configuration found corresponds to the last one of this vector.
A matrix with configurations as columns and instances as rows. Column names correspond to the internal identifier of the configuration (
A matrix with columns
time. This matrix contains the log of all the experiments that irace performs during its execution. The instance column refers to the index of the
scenario$instancesListdata frame. Time is saved ONLY when reported by the
A logical vector that indicates if a soft restart was performed on each iteration. If
FALSE, then no soft restart was performed.
A list that contains the state of irace, the recovery is done using the information contained in this object.
A list that contains the testing results. The elements of this list are:
experimentsa matrix with the testing experiments of the selected configurations in the same format as the explained above and
seedsa vector with the seeds used to execute each experiment.
This function checks the correctness of the scenario, reads the
parameter space from
prints its results in various formatted ways, (optionally) calls
psRace() and, finally, evaluates the best configurations on the test
instances (if provided). If you want a lower-level interface that just
runs irace, please see function
