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. If local buyers cannot find you, the phone does not ring. Marketing Monday Lunch + Learn is a monthly working lunch for Columbus business owners focused on building relationships, local networking, and local marketing. Every kind of local business welcome. No pitch round, no pressure, no upsell. **This month** Most local businesses pick one or two places to be visible and call it good. The result is inconsistent calls and a feeling that marketing is not working. We will walk through the three places every local business needs to show up, plus the fourth place most owners ignore that quietly produces the warmest leads. **What to expect** Doors open at noon. 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.

**How to Get Off-Market Deals With Direct-to-Seller Marketing** Want to learn how to get off-market deals through direct-to-seller marketing without relying on agents, wholesalers, or the MLS for consistent deal flow? That is exactly what we are covering at this next Columbus Investors Club Meetup. Get Your Free Ticket **[HERE](https://www.eventbrite.com/e/how-to-get-off-market-deals-with-direct-to-seller-marketing-tickets-1987845260686?aff=cicmeetupapp)**[ ](https://www.eventbrite.com/e/how-to-get-off-market-deals-with-direct-to-seller-marketing-tickets-1987845260686?aff=cicmeetupapp)🎟️ Most investors who try to do off-market deals make the same mistake: they throw money into a marketing channel, pray that it works, and hope a deal comes out the other side. There is no real strategy, no clear math, no tracking, and no process to know what is actually working. At this meetup, we are going to break down how to reverse engineer direct-to-seller marketing using our SCALE framework so you can approach your marketing with more clarity, confidence, and consistency. We will cover how to think through inbound, outbound, and free marketing channels, how to choose the right channel for your goals, how to run the numbers before you spend, how to allocate the right budget, how to launch the campaign correctly, and how to evaluate and track performance so you can make better decisions moving forward. **SCALE Framework:** **S –** Select the right channel **C –** Calculate the numbers **A –** Allocate the budget **L –** Launch the campaign **E –** Evaluate and track it **What We’ll Cover** * How to get off-market deals through direct-to-seller marketing * How to stop guessing and start reverse engineering your marketing * The difference between inbound, outbound, and free marketing channels * How to choose the right channel for your business and market * How to calculate the numbers before launching * How to allocate a budget based on goals, not emotion * How to launch and track a campaign the right way * How to create more consistent and predictable deal flow **Date:** May 28, 2026 (Thursday) **Time:** 6 - 8pm EST **Location:** Ohio Brewing Company, 421 E 2nd Ave, Columbus, OH 43201 **Save Your Seat** → https://www.eventbrite.com/e/how-to-get-off-market-deals-with-direct-to-seller-marketing-tickets-1987845260686?aff=cicmeetupapp **FREE DRINKS & FOOD PROVIDED!** **About Columbus Investors Club** The Columbus Investors Club is a local meetup for real estate investors, aspiring investors, contractors, vendors, lenders, realtors, and other professionals who want to grow in the Columbus market.
