Happy to share the video of the presentation about my initial work on a VRP heuristics framework, at the @DIMACSChallenge Workshop.
It sure has been a great experience, full of exciting people and insightful presentations.

VRPSolverEasy is the first practical tool for the exact solution of VRPs: (1) User-friendly; (2) Covers most classic variants and their combinations; (3) Small running times up to a respectable instance size (like 100 customers) @rrsadykov @najibprog @edu_queiroga
