Dataset / solver notebooks¶
Demo and analysis notebooks for the data-generation side. Each page links to the source notebook, which you can open on the Hugging Face Hub or download and run locally.

-
Getting started
The shortest path from the dataset to a training example: load one released scene, decode its tensor, draw a reference route and turn it into a segmentation target.
-
Obstacles
Obstacle masks from least to most covered, drawn coverage against its target, and the detour that obstacles force on the optimal route over a whole validation split.
-
The three objectives
What the
elevation,slope_uphillandenergyobjectives reward on one scene, their elevation profiles, and the extra cost of a route optimised for the wrong objective. -
Exact re-solve
Solves stored labels again with the exact float64 A* reference, compares costs and routes, shows why the search budget matters, and repeats the check on a sample of validation scenes.
-
Timing a planner
Times the canonical A* planner of
passage-evalwith the practices that make a timing meaningful: warm-up, repetitions, percentiles and a stated machine.
