getConfigurationByIteration function

Returns the configurations by the iteration in which they were executed.

getConfigurationByIteration(iraceResults, iterations, drop.metadata = FALSE)

Arguments

• iraceResults: list()|character(1)

  Object created by irace and typically saved in the log file irace.Rdata. If a character string is given, then it is interpreted as the path to the log file from which the iraceResults object will be loaded.

• iterations: integer()

  The iteration number or a vector of iteration numbers from where the configurations should be obtained. Negative values start counting from the last iteration.

• drop.metadata: logical(1)

  Remove metadata, such as the configuration ID and the ID of the parent, from the returned configurations. See removeConfigurationsMetaData().

Returns

A data frame containing the elite configurations required.

Examples

log_file <- system.file("exdata/irace-acotsp.Rdata", package="irace", mustWork=TRUE)
getConfigurationByIteration(log_file, iterations = c(-2, -1), drop.metadata = TRUE)
