Timefold

Abstract

Most optimization solvers require the business constraints and objectives as math equations. Timefold Solver is different. It’s an open source solver that accepts them as plain Java or Python code. That means the constraints can reuse existing code, such as date and time libraries and don’t face any linear or quadratic limitations.

In this session, I’ll explain the basics, demonstrate a vehicle routing implementation and live code a school timetabling model.
