## Scenario setup for Iterated Race (iRace).
############################################################################

## To use the default value of a parameter of iRace, simply do not set
## the parameter (comment it out in this file, and do not give any
## value on the command line).


## File that contains the description of the parameters.
parameterFile = "parameters.txt"
configurationsFile = "default.txt"
forbiddenFile = "forbidden.txt"



## Directory where the programs will be run.
execDir = "."



## Directory where tuning instances are located, either absolute path or
## relative to current directory.
trainInstancesDir = "instances/small/training/"


## Set testing data 
testInstancesDir = "instances/small/testing/"
testNbElites = 5



## The maximum number of runs (invocations of targetRunner) that will performed. It
## determines the (maximum) budget of experiments for the tuning.
maxExperiments = 300



## Number of CPU cores to use
parallel = 3



## A value of 0 silences all debug messages. Higher values provide
## more verbose debug messages.
# debugLevel = 0



## Target runner
## Bash script that executes the target algorithm
targetRunner = "./target-runner"

## R function that executes the target algorithm
##targetRunner = function (experiment, scenario) {
##  suppressMessages(require("stringr"))
##
##  #comment this line to execute acotsp!
##  #return(list(cost=runif(n=1, min=100, max=2000)))
##
##  # Target algorithm executable   
##  exe = "ACOTSP-1.03/acotsp"

##  candidate_id  = experiment$id.configuration
##  instance_id   = experiment$id.instance
##  seed          = experiment$seed 
##  instance_name = experiment$instance
##  
##  # Define fixed parameters (budget or other options)
##  fixed_params = "--tries 1 --time 0 --tours 1000 --quiet"
##
##  # Create parameter arguments for command line
##  parameters    = buildCommandLine(experiment$configuration, experiment$switches)
##
##
##  # Create command line
##  command_line = paste (fixed_params, "-i", instance_name,"--seed", seed, parameters, sep=" ")
##
##  # Execute command
##  output = system2(command=exe, args=command_line, stdout=TRUE, stderr=TRUE)
##
##  # Check if error!    
##  if (!is.null(attr(output, "status"))) {
##    cat ("\nError executing: ", exe, command_line, "\n")
##    cat (output, "\n\n")
##    stop()
##  }
##
##  # Parse output 
##  sel = which(sapply(output, grep, pattern="try 0, Best", ignore.case = FALSE, value=FALSE) == 1)
##  result = as.numeric(str_split(str_trim(str_split(output[sel],"," )[[1]][2]), "\\s")[[1]][2])
