Function: parseBenchmarkParameters()

parseBenchmarkParameters(params: BenchmarkParameters, args: string[]): BenchmarkParameters

Parse benchmark parameters from command line arguments.

Parameters​

ParameterTypeDescription
paramsBenchmarkParametersInput/output argument. Contains default values of parameters that will be overridden by command line arguments. When not specified, empty object {} is used.
argsstring[]Command line arguments to parse. When not specified, process.argv.slice(2) is used.

Returns​

BenchmarkParameters

Remarks​

This function parses command line arguments. In case of an error it prints an error message and terminates the program. The default parameters can be specified using the parameter params.

When --help or -h is specified, then the function prints the params.usage string followed by the description of supported benchmark and engine parameters, and then terminates the program.

The description of supported parameters looks like this:

Benchmarking options:
  --nbSeeds uint32        Test models on the given number of random seeds
  --nbParallelRuns uint32 Run given number of solves in parallel
  --minObjective double   Require given minimum objective value
  --maxObjective double   Require given maximum objective value
  --dontSolve             Not really solve. Useful e.g., with --exportJSON

Overall benchmarking output:
  --output fileName      Write detailed results of all runs into a JSON file
  --summary fileName     Write a summary table of all runs into a CSV file
  --dontOutputSolutions  Do not write solutions into the output file (save space)

Outputs for individual benchmarking runs:
  --result fileNamePattern         Write a detailed result into a JSON file
  --log fileNamePattern            Write log into the specified text file
  --exportJSON fileNamePattern     Export problem into a JSON file
  --exportTxt fileNamePattern      Export problem into a text file
Where fileNamePattern undergoes the following expansion:
  {name}       ->  Model name (by convention name of the source data file)
  {flat_name}  ->  Like {name} but all characters '/' is replaced by '_'
  {seed}       ->  Random seed
Solver path:
  --solverPath string              Path to the solver

Terminal output:
  --color Never|Auto|Always        Whether to colorize output to the terminal

Major options:
  --nbWorkers uint32               Number of threads dedicated to search
  --searchType LNS|FDS|FDSLB|SetTimes
                                   Type of search to use
  --randomSeed uint32              Random seed
  --logLevel uint32                Level of the log
  --warningLevel uint32            Level of warnings
  --logPeriod double               How often to print log messages (in seconds)
  --verifySolutions bool           When on, correctness of solutions is verified

...

WorkerParameters can be specified for individual workers using --workerN. prefix, and also for worker ranges using --workerN-M. prefix. For example:

  • --worker0.searchType FDS sets the search type to the first worker only.
  • --worker4-8.noOverlapPropagationLevel 4 sets the propagation level of noOverlap constraint for workers 4, 5, 6, 7, and 8.
