Default Objective¶

Overview¶

The Default Objective is a thin wrapper that currently inherits all behavior from the Distance Objective. That means, by default, route optimization will focus on minimizing total distance traveled across all vehicles. Use it as a baseline or fallback when you have not explicitly selected another objective (cost, duration, etc.).

When to Use¶

When you haven't specified a particular optimization preference.
As a starting point for testing before choosing specialized objectives.
When you want a balanced, general-purpose optimization approach.
For simple routing scenarios where distance minimization is acceptable.

Behavior¶

Inherits all behavior from the Distance Objective.
Only considers distance cost (per_km) for optimization.
Fixed costs (fixed) and time-based costs (per_hour) are ignored.
Default per_km value of 1000 is applied if not specified.
Provides consistent baseline performance across different problem types.

General Validation¶

All validation rules from Distance Objective apply.
Ensure every vehicle has a non-negative per_km cost defined.
Vehicle capacity and job demand must be valid and consistent.
Distances between locations must be accurate or computable.
No additional validation requirements beyond standard distance optimization.
