Peel¶
Route roads by steepest descent down the access-depth peel: every interior parcel links to a neighbour one BFS ring shallower, and each chain roots at the nearest street point. The union is a connected centreline network that reaches every parcel — full access by construction. It is the project's deterministic access-optimal baseline: it shows the ceiling on access improvement, and its cost (road length, fragmentation, zero regard for what is buildable) is the price of that ceiling.
Configuration: conf/method/peel.yaml
Single-block k-complexity runs¶
Access depth is peel-k: the number of BFS rings between the deepest parcel and a street (k after = 1 means every parcel fronts a road). road components counts disconnected pieces in the proposed network — 1 is a single buildable network. Read from the outputs/*/run.log evaluation logs on disk:
