multi_irace function

Execute irace() multiple times with the same or different scenarios and parameter space definitions.

There are three modes of operation:

• One scenarios and k parameters: k runs with the same scenario and each parameter space definition.
• One parameters and k scenarios: k runs with the same parameter space definition and each scenario.
• k parameters and k scenarios: k runs with each scenario and parameter space definition.

Each of the k runs can be repeated n times by supplying a value for n.

multi_irace(
  scenarios,
  parameters,
  n = 1L,
  parallel = 1L,
  split_output = parallel > 1L,
  global_seed = NULL
)

Arguments

• scenarios: list()

  A list of scenarios. If only a single scenario is supplied, it is used for all parameters.

• parameters: list()

  A list of parameter space definitions. If only a single definition is supplied, it is used for all scenarios.

• n: integer(1)

  The number of repetitions.

• parallel: integer(1)

  The number of workers to use. A value of 1 means sequential execution. Note that parallel > 1 is not supported on Windows.

• split_output: logical(1)

  If TRUE, the output of irace() is written to {execDir}/run_{i}/irace.out

  instead of the standard output.

• global_seed: integer(1)

  The global seed used to seed the individual runs.

Returns

A list of the outputs of irace().
