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!

## Learn Go and NixOS deployments with large language models Hello, 世界! When used sensibly, language models can be tutors, too. For meetup #60 on Tuesday [May 26, 2026 19:00 CET](https://www.meetup.com/leipzig-golang/events/312537727) we are really happy to have [Maxime](https://www.linkedin.com/in/plumps/) dive into Nix/NixOS with the help of language models. Nix is a functional package manager and its immutable traits enable robust, reproducable deployments of Go (and other) projects. The high level goals of Nix/NixOS are similar to other immutable Linux distributions, like [Silverblue](https://fedoraproject.org/silverblue/) or [Bazzite](https://bazzite.gg/). Becoming familiar with the Nix configuration language can be a challenge, but one that a well instructed tutor may help with. > Artificial intelligence techniques are increasingly used in education to enable personalized learning and intelligent tutoring [LLM Agents for Education: Advances and Applications](https://aclanthology.org/anthology-files/anthology-files/pdf/findings/2025.findings-emnlp.743.pdf) (11/2025) Why reproducible and immutable deployments play a role? [Justin Garrison](https://justingarrison.com/blog/state-of-immutable-linux/) says: > It’s 2026, if you’re not using something immutable (or at least reproducable) you’re doing more maintenance work than you should. [blog post recapping talk from [Southern California Linux Expo 23x](https://www.socallinuxexpo.org/scale/23x)], 03/2026, PASADENA, CA ### Schedule * 18:45 Doors open * 19:00 Welcome * 19:10 Dive into Nix/NixOS with LLMs * 19:50 Open discussion We’ll meet: * in person at [Basislager Leipzig](https://basislager.co), at [Peterssteinweg 14, 04107 Leipzig](https://maps.app.goo.gl/1fMkeDSPZ7Aauszh8) ([OSM](https://www.openstreetmap.org/node/3504864558)) * and online via [Google Meet](https://meet.google.com/poy-koue-spc) Join us to discuss robust Go deployments, language models as learning tools and more!

Tatry IT Ťa pozýva na pravidelné stretnutie o aktuálnych a zaujímavých (nie len) digitálnych a IT témach. Eventy organizujeme v spolupráci s [Coworking Poprad](https://coworkingpoprad.sk). Príď na meetup Tatry IT Community na tému: Priamy let na produkciu: AI-first vývoj v Kiwi.com. Platformu Kiwi.com netreba špeciálne predstavovať. Menej sa však hovorí o tom, ako Kiwi.com funguje vo vnútri. Na meetupe budeme hovoriť o tom, ako v Kiwi.com beží (lieta) AI-first vývoj. **Speaker: Michal Cyprian** Zaregistruj sa [tu](https://docs.google.com/forms/d/e/1FAIpQLSc6wDQ2F7Z_avxdFvhSzJddNjr2i4h231A_q0TDzIFhqRyzVw/viewform). Slido: #tatryit **PROGRAM:** 18:00 Privítanie 18:10 Priamy let na produkciu: AI-first vývoj v Kiwi.com 19:00 Q&A a Networking Event budeme [streamovať](https://youtube.com/live/ltR3RmE2uT0?feature=share) a môžete si ho pozrieť aj neskôr na YouTube kanáli Tatry IT community (https://youtube.com/live/ltR3RmE2uT0). Zaujíma Ťa niečo konkrétne, alebo máš zaujímavú tému? Napíš nám (community@tatryit.sk). Tatry IT Team

Why are we unhappy? Where does emotional pain come from? Studies show that people who suffer from long-term emotional pain have painful experiences in their lives that were never fully resolved in their mind. In other words, there were issues in the past that were not completely dealt with. This can include abuse in childhood, breakups, divorce, death of a loved one, to name a few. How do you know whether you have gotten over something painful? Here is an easy test: Do you still have attention on what had happened to you? For instance, do you still find yourself thinking about something painful that you went through? If you are, then you are not over it. In fact, in severe cases, people find themselves playing a "tape" in their mind over and over again. So how do you heal from your past? How do you stop the "tape" playing in your mind? In this meeting, you will learn a technique to help you with that. Come join us! Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there.
