The new overview of our REST API for Field Service Routing is now online. Take a look: app.timefold.ai/models/field-s… It covers almost every constraint. From time windows, fairness and technician costs to real-time planning and many other #PlanningAI requirements. Just pick and choose

One of the most interesting feats of engineering recently was explained Saturday at #Fosdem for project Liliput for #Java OpenJDK: How to put 25 bits into 2 bits. How they are circumventing the trade-off between usability and memory usage. 🧵 bsky.app/profile/geoffr…

How I built an AI company to save my open source project On this day, 3 years ago, my world fell apart. It was a Thursday. I just finished my second meeting that morning, looked at my inbox and realized it was over. My life’s work was over. OptaPlanner, the popular open source

Most publications of the Vehicle Routing Problem only cover the tip of the iceberg. Benchmarks and academic papers typically only handle vehicle capacity (CVRP) and time windows (VRPTW) But production deployments also need to deal with many other requirements.

Can LLMs solve scheduling or routing problems? Can GenAI help companies save millions of dollars by optimizing Vehicle Routing, Shift Rostering or Job Scheduling to increase productivity and retention? Why not? Which type of AI can? And how can we combine it with LLMs to make

This is what happens if you use floating point numbers (int, double in #Java) for financial data. Use decimal numbers (BigDecimal in Java) instead.

That moment when your backend algorithms optimize a vehicle routing dataset with thousands of visits... ... and your frontend turns it into a piece of modern art.

A great plan is worthless if you can't explain why. For the operators to trust your software, they need more than a button to "Schedule with AI" that generates the optimized schedule for their employees. They need explainability. Learn how: timefold.ai/blog/explainab…

Can the optimal solution for a Traveling Salesman Problem (TSP) have crossing paths? No, it cannot. Because of the Triangle Inequality principle. But in reality, it can. Because there's road infrastructure: highways, one-way streets, etc. In the real-world, solution optimality
