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!

This is the 50th Anniversary of the Judgment of Paris. Significantly, in 1976, California wines unexpectedly outperformed French wines in a blind tasting with nine French judges, challenging the perception that only French wines were of the highest quality. This event helped elevate the status of California wines on the global stage and is considered a pivotal moment in wine history. House Wine, in Worthington, modestly, recreates that moment in history with a tasting both American and French wines in a fun, casual atmosphere. Come at 6:45, pay your fee at the register and join your friends for this "Judgey" tasting. https://www.wineenthusiast.com/culture/wine/the-judgment-of-paris-turns-40/ Arrive when you can and we'll have a table for gathering. Feel free to bring your own food as it is welcomed at this local gem or order from the newly opened Worthington Inn, or local favorites such as Dewey's, Everest, Jet, Worthington Tavern and The Whitney. Each person pays their tasting fee, typically $15, and gets their wine glass, then approximately five pours of the wines being served. **Parking is tough**. Try the second lot behind House Wine accessed by the land by the back parking lot or the municipal lot one block north of House Wine. **Waiver and Liability and Attendance Policy.** Participation by you and your guests means you agree to the Waiver of Liability and Attendance Policies on our Group Page.

She has exposed her legs in a biblical city, an act they deem forbidden, and their judgement will echo on through her adolescence. When our narrator finally admits to her mother that she is queer, her mother's response only intensifies a sense of shame: 'You exist too much,' she tells her daughter. Told in vignettes that flash between the U.S. and the Middle East--from New York to Jordan, Lebanon, and Palestine--Zaina Arafat's debut novel traces her protagonist's progress from blushing teen to sought-after DJ and aspiring writer.

Let's grab some coffee/food and share a morning chat! The East Market has an ample parking lot and outdoor and indoor seating. Grab a cup of coffee from Winston's Coffee & Waffles or on your way to East Market and meet us on the second floor - table behind or east of the elevator. Per what this group is about: "Everyone is welcome! International transplants to Columbus who want to improve language skills, Columbus residents who enjoy talking to people from other countries, and those who would like to discuss international travel and culture, and who enjoy getting together for good conversations."

5:45-7:45 in Conference Room B, Library lower level. Bring your yarn projects, meet new friends. If you plan to attend, please RSVP yes. If you can’t attend, please change your RSVP to no. This helps anyone who is waitlisted and it allows me to have an accurate count of attendees as our space is quite limited. Plenty of parking in the lot, in the overflow lot across the street, and on the street. See you there!
