Combinatorial optimization problems arise across logistics, scheduling, and engineering, and C++ remains a language of choice when performance matters. This lecture takes a practical look at solving such problems in C++, using the Electric Vehicle Routing Problem as a running example. We begin with an exact solver, formulating the problem as a mixed-integer program and trying to solve it through GLPK's C API directly from C++. Exact methods, however, quickly hit their limits on real-world instances. The second half of the talk turns to metaheuristics: how they are designed, why C++ is particularly well suited for implementing them, and what design choices matter most in practice. We'll walk through a concrete implementation, touching on data structures for fast neighborhood evaluation, generic algorithm design with templates, and the performance considerations that separate a prototype from a production-ready solver. The goal is not to advocate for one approach over another, but to show how C++ supports the full spectrum of optimization techniques. # About Speaker Luka Matijević is a researcher at the Mathematical Institute of the Serbian Academy of Sciences and Arts, whose work bridges academic research and freelance engineering. He's drawn to identifying the right algorithm for a given problem — and to the kind of careful optimization captured by one of his favourite Futurama lines: *"When you do things right, people won't be sure you've done anything at all."* ## 📅 Event Details | | | | --- | --- | | 👤 **Speaker** | **[Luka Matijević](https://www.linkedin.com/in/luka-matijevic/)** | | 🕕 **Date & Time** | **27th of May (Wednesday), 6 pm** | | 📍 **Location** | **Beograđanka, Vidikovac, 22nd floor** | | 🏢 **Address** | **Masarikova 5** | | 💻 **Online** | **[C++ Serbia YouTube](https://www.youtube.com/@cppserbia)** | See you!

Monthly working lunch for Columbus business owners. One specific topic, one to three actions you can run this week. You can be the best at what you do and still be invisible.

No pitch round, no pressure, no upsell. **This month** Most local businesses pick one or two places to be visible and call it good.

Order lunch and drinks at the cafe counter or bring your own. You get real conversation with other local owners and a focused marketing lesson. You leave knowing people and with one to three actions to run that week. The room is reserved through 1:30 PM. **Who this is for** Any local business owner who wants clearer marketing direction and real local relationships. Service businesses, retail, home services, professional services, online owners building local presence, anyone serious about being part of the Columbus business community. **Not the right fit if** You are here to pitch the room or recruit for an MLM. **Details** * Second Monday of every month * 12:00 to 1:30 PM * Good Cafe Easton, 4400 Easton Commons, Ste 150, Columbus, OH 43219 * Order lunch and drinks at the counter when you arrive * Free to attend, RSVP required, space is limited **About the host** Rita Suzanne is a local marketing strategist and the founder of Local Marketing Method.
