about

Hi, my name is Leon! I'm building route optimization software at RoutingLab. I'm also completing my PhD at the Vrije Universiteit Amsterdam, researching machine scheduling and vehicle routing problems motivated by industrial applications.

Check out PyVRP and PyJobShop — two open-source projects I've worked on in this space.

software

• PyVRP — state-of-the-art vehicle routing problem solver
• VRPLIB — read and write vehicle routing problem instances
• PyJobShop — constraint programming for machine scheduling
• ALNS — adaptive large neighborhood search metaheuristic

consulting and custom development

Have a tough combinatorial optimization problem to solve? I design custom algorithms and implement CP-SAT and MIP models.
