Hillwalking

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!

# Stop Scrolling. Start Living. Sometimes the best way to meet new people is simple **get out of the house and do something in real life.** With weather still unpredictable, we’re keeping this one simple **we’ll be walking indoor or outdoor at Polaris.** Most people who attend often come alone. **This is a casual social walk designed to meet new people.** No awkward networking. No pressure. Just walking, talking, and good company. Whether you're new to the group or a regular, this is a great way to **get some steps in, meet new people, and do something different on a Tuesday evening.** Location **Polaris Fashion Place** **Meeting Spot:** Outside or just inside **"Dicks Main entrance"** from parking lot Look for the **Meetup sign and green or gold wristbands.** The Plan **6:45 PM — Meetup / Check-in** Arrive, say hello, meet a few people, and get checked in. *The first 15 minutes are usually the best time to meet people before we start walking.* **7:00 PM — Walk Starts (Sharp)** We’ll begin a **casual indoor or outdoor social walk around Polaris Mall.** by the end of the hour we should be near 3 miles approx. 6k steps **8:00 PM — Walk Ends** Anyone who wants to keep the fun going can join us for Topgolf. **Optional Activity** After We’ll head over to **Topgolf** No golf experience needed — **beginners welcome.** **Let’s** **see your best Happy Gilmore swing!!!** To reduce no-shows and keep events sustainable: **$2 — Walk RSVP** **$15 — Optional Topgolf add-on** or **$17 TOTAL** Topgolf is **limited to the first 6 paid players per bay.** If the first bay fills, I’ll open another lane if enough people want to join. **To keep group sizes manageable and reduce no-shows, this event is limited to paid attendees. RSVP alone does not reserve a spot.** Use payment link in comments to confirm your reservation. Even if only 1 person signs up and confirms their rsvp the event will happen! **Important** RSVP alone **does not guarantee a spot.** Paid attendees receive: • Event wristband • Guaranteed Topgolf spot (if purchased) • Inclusion in group activities Why These Events Exist Wise Unlimited events exist to help people: • meet new friends • get off their phones • **do more things in real life** Too many people **want to go do things** but **don’t want to go alone.** This solves that. **Stop scrolling. Start doing stuff.**

Hi ladies. We will meet in front of the Nature Center and head to the two Observation decks. We will then hike Hickory Ridge, Ripple Rock, Overlook and Sugarbush trails to get approximately four miles total distance. We will walk approximately a 18 minute mile pace. Please wear appropriate hiking shoes.

We'll get in around 4 miles at Three Creeks Metro Parks, primarily natural trails. 17-18 minute miles, no one left behind, and faster walkers are free to lead out. Optional lunch after! If you're joining for hiking all the metro parks, this is the sixth one!

**Not everyone will come. That is exactly why you should.** **Two for Tuesdays** is for the people who actually want to get out and do something instead of just talking about it. We’re kicking off the night with a one-hour social walk before Duckpin Social. **Expect a laid-back** But an Intentional 1 hour walk (2-3 miles), good people, and a better way to spend your Tuesday than staying home and doing the same thing you always do. **If the weather does not cooperate, we’ll move indoors.** **This is a paid event.** A small contribution helps keeps events sustainable and ensures those **who RSVP actually show up.** Payment **Link Found in comments** or you can pay on Venmo, Paypal, @WiseUnlimitedLLC or Cashapp $WiseUnlimitedLLC. Walk RSVP **$2** Walk / DuckPin Social **$5** Walk / DuckPin Social + 1 game of duckpin **$12** Please be sure **to Put Event and Event Date** in the note when paying RSVP Fee
