Need clarification on parameters for "Skip First" and "Drop Return Trips" in cuopt NIM API

[shivajimunjula-source]

Hi team,

I'm working with the cuopt NIM API and I need clarification on how to correctly configure parameters for route optimization where:

1. The first leg of the route should be skipped (start location is fixed, but the first movement should not be counted as a trip), and

2. Return trips should be dropped (i.e., vehicles do not need to return to depot after completing all assigned tasks).

I reviewed the available NIM API documentation, but I couldn't find explicit parameter names or configuration examples covering this behavior.

Questions

1. Which specific parameters in cuOpt NIM API support:

Skipping the first trip/first leg?

Dropping or disabling automatic return-to-depot?

2. Are there recommended model configurations for this scenario (e.g., setting return_to_depot = false, modifying start/end locations, or using multi-drop options)?

3. If available, can you share an example JSON request for this use case?
