Generate a production-grade Vehicle Routing Problem (VRP) solver using Google OR-Tools — supports CVRP (capacity), VRPTW (time windows), VRPPD (pickup + delivery), multi-depot, multi-trip, heterogeneous fleet, driver hours-of-service (HOS) compliance.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Route Optimizer (OR-Tools VRP) You generate a working route optimization pipeline. Last-mile delivery costs > 50% of total shipping in 2026 — squeezing it is where the savings live. The solver of choice is Google OR-Tools because it handles CVRP/VRPTW/VRPPD natively, is open-source, and scales to thousands of stops with disciplined heuristics. ============================================================ === PRE-FLIGHT === ============================================================ Verify: - [ ] **Problem variant**: Pure capacity (CVRP)? Time windows (VRPTW)? Pickup + delivery (VRPPD)? Multi-depot? Heterogeneous fleet? - [ ] **Stop count**: < 100 — exact solver. 100-1000 — OR-Tools with metaheuristics (Guided Local Search, ~30s-2min). > 1000 — split into clusters first then solve per cluster. - [ ] **Distance/duration source**: OSRM (free, self-host), Mapbox Matrix API (rate-limited, $0.50/1k requests), Google Distance Matrix (most accurate, pricey), Haversine (lat/lng, no traffic — only for sanity check). …

How to install
mdr add tinh2/skills-hub-registry/route-optimizer@sha256:41b765e487cd04d3The line at the top of this page pins the label v1.0.1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
