New VRP Variant
Planets are customers. Spacecraft are vehicles. Orbital mechanics replace road constraints — Hohmann transfers define the cost function.
Open Research Platform
Interplanetary
Vehicle Routing
A novel formulation of the VRP where vehicles are spacecraft navigating gravitational constraints, transfer windows, and multi-planet supply chains across the solar system.

The IVRP Project
ALNS Metaheuristic
Adaptive Large Neighbourhood Search with mission-aware destroy/repair operators. Respects Δv budgets and time windows.
3D Solar System
Real Keplerian orbital data drives a Three.js simulation. Watch spacecraft travel transfer arcs between planets in mission time.
Porkchop Plots
C₃ energy maps over departure × arrival date space. Identifies optimal launch windows across all planetary pairs automatically.
Mission Metrics
Track total Δv, mission duration, fleet utilization and leg completion in real-time as the simulation clock runs forward.
Open Source
Algorithms, simulation, and formal proofs fully open. Upload any mission JSON and watch it visualize in 3D.
