Options

A reference for the options to configure vehicle routing.

If both an environment variable and its corresponding CLI flag are defined, the CLI flag will overwrite the environment variable.

Go

These are the default options that are available with the go-nextroute community app and the Nextmv routing app.

Valid time units for -solve.duration are as follows, according to time.ParseDuration from Go's standard library:

  • ns (nanoseconds)
  • us/µs (microseconds)
  • ms (milliseconds)
  • s (seconds)
  • m (minutes)
  • h (hours)

The solve duration is displayed in ns in the output.

The units for options that deal with time duration (such as -solve_duration) are seconds. This applies for the input and output as well.

Output

Most options are parsed to the output, under the options key. Here is an example of a Go app.

When working with a custom app, you may also modify the options in code, which would override the ones passed from the runner. Here is an example of how this is done and how the resulting output shows the modified options. Notice that options is modified multiple times inside the solver function.
