buildCommandLine function

Generate a command-line representation of a configuration

buildCommandLine receives two vectors, one containing the values of the parameters, the other containing the switches of the parameters. It builds a string with the switches and the values that can be used as a command line to call the program to be tuned, thus generating one candidate configuration.

buildCommandLine(values, switches)

Arguments

• values: A vector containing the value of each parameter for the candidate configuration.
• switches: A vector containing the switches of each paramter (in an order that corresponds to the values vector).

Returns

A string concatenating each element of switches and values for all parameters with a space between each pair of parameters (but none between the switches and the corresponding values).

Examples

switches <- c("--switch1 ", "--switch2-", "--switch3=")
values <- list("value_1", 1L, sqrt(2))
buildCommandLine (values, switches)
## Build a command-line from the results produced by a previous run of irace.
# First, load the data produced by irace.
logfile <- file.path(system.file(package="irace"), "exdata", "irace-acotsp.Rdata")
iraceResults <- read_logfile(logfile)
allConfigurations <- iraceResults$allConfigurations
parameters <- iraceResults$scenario$parameters
apply(allConfigurations[1:10, unlist(parameters$names)], 1, buildCommandLine,
      unlist(parameters$switches))
