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!

Здравейте, WordPress хора! Както знаете, благодарение на Matt Mullenweg и Mike Little, на 27 май 2003 г. един млад проект с отворен код направи първите си стъпки в света - и ето ни 23 години по-късно, все още влюбени в него. Двама души го създадоха, но хиляди доброволци, разработчици, дизайнери и ентусиасти по целия свят го превърнаха в това, което е днес. Затова на 27 май 2026 г. отново ще се съберем в София, за да вдигнем тост (и хапнем парче торта) за рождения ден на любимата ни платформа! Какво ни очаква? Среща с хора, които говорят на нашия език - този на темите, плъгините, къстъмизациите и късните нощи в WordPress редактора. Очакват ни разговори, хапване, торта и онова специално усещане, когато общността се събере на едно място. Докато ние празнуваме в София, хиляди WordPress ентусиасти по целия свят правят същото – а ние сме част от тази голяма картина. Без значение дали си разработчик с 15 години стаж, дизайнер, който прави първия си сайт, блогър, агенция или просто човек, който обича отворения код – има място за теб на тази маса. Малко повече инфо: 🎟️ Събитието е напълно безплатно. Единственото, което трябва да направите, е да се регистрирате в събитието в Meetup.com. 📍 Мястото? Добре познатото ни Sky Beauty Lab! 👕 Донеси любимият си суаг! Извади от гардероба най-готината WordPress тениска, шапката с логото, чорапите с Wapuu – каквото имаш. И не забравяй да публикуваш снимки с хаштаговете #WP23 и #WP23Sofia, за да покажем на света как празнува българската общност. Благодарности: Това парти нямаше да е възможно без партньорите ни, които стоят зад WordPress Sofia Meetup и общността ни вече години наред – [SuperHosting.BG](SuperHosting.BG), [Delta.BG](Delta.BG), [Jump.bg](Jump.bg) и [JetHost.BG](JetHost.BG). Благодарим ви, приятели! <3 Заредете доброто си настроение, отворете календара и си запазете датата. За тези, които не знаят: месечните срещи на WordPress Sofia Meetup събират десетки хора (независимо дали са професионалисти или абсолютно начинаещи), които по някакъв начин са свързани с най-използваната система за управление на съдържанието в света. Те са напълно безплатни и отворени за всички, които обичат WordPress - единственото нещо, което трябва да направите, за да присъствате, е да се регистрирате в събитията тук. Очакваме ви!

*This event features presentations in both English and Bulgarian.* Силен старт на крипто лятото! Миналия месец се надявахме, че сме оцелели след дъното. Този месец видяхме токени, които се покачиха с до 50%. Изглежда не сме сгрешили. След месеци на спадове, несигурност и пазар, който дълго време изглеждаше изтощен, нещо най-после се размърда. И не само на графиките. Имаме три добри новини за този месец: Първо, пазарът показа зъби. Второ, САЩ продължават да бутат напред с добра крипто регулация. Трето (и може би най-забавното): Prediction Markets се оказаха толкова успешни, че България реши да ги блокира (за първи път още през февруари). Когато регулатор бърза да забрани нещо, обикновено това е знак, че там се случва нещо интересно. На следващия Sofia Crypto Meetup ще обсъдим: Кои токени се представиха най-добре и защо. Какво всъщност представляват Prediction Markets и защо толкова много хора (и държави) говорят за тях. Какво може да очакваме през лятото - кои са реалните сценарии, а не магическите прогнози. Никакви празни приказки, никакви обещания за бързо забогатяване. Просто разговор по същество, добър анализ и достатъчно време за въпроси и дискусия. Елате да го отпразнуваме заедно. Дъното е зад нас, лятото е пред нас, а разговорът ще бъде интересен. Очаквайте и много специален гост!

This is a free, in-person meeting on the subject of betrayals, losses and how to get over them so you can build lasting relationships. Burdened by a stressful relationship? Unhealthy relationships can trigger feelings of anger, despair or self-doubt. They can create dwindling spirals of fights and seeking to make-up, or trying to “pin the blame” on someone or something. If you don’t find the RIGHT reasons, or select the correct sources of the problem, the problem can just get worse and worse. Whether in love or personal ties, with friends or at work, our life really IS affected by the quality of our relationships. Good ones can promote pleasure and survival while less optimum ones can lead to annoyance, anger, self-doubt, stress, or even affect our health and ability to survive well. Whether you are suffering from a divorce, or a painful break-up, don’t know who to trust (or who to CHOOSE) as a partner, friend, boss or employee - the anxiety of relationship troubles can really make a mess of things. Maybe you’ve suffered a betrayal, or are dealing with hostility or criticalness or invalidation. Dwindling relationships can involve destructive behavior, where we hurt those we love, or start succumbing to self-destructive thoughts, attitudes or behaviors that spiral out of control and affect much more than our immediate relationship. Past losses in love or life can affect how we act or react to new people and situations and hold us back from even starting to create new, possibly great relationships! How can one get back onto a saner course of action? Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life: human relationships! Break free from self imposed limitations Here we will discuss: • How to “erase” the trauma of past hurts and betrayals so that one isn’t always repeating past mistakes. • Why and how do the negative emotions of others affect you? • Why is my partner withdrawing and what can I do about it? • Why do we sometimes feel compelled to hurt the ones we love? • Fights & arguments - what's really behind them? • What underlies “corrosive criticism” or the need to invalidate self or others? • How one can stably change one’s outlook on life so they can affect positive change? • Where do compulsive destructive behaviors come from and what can be done about them? • How to form closer bonds & keep growing the relationships with the people you care about? • How to enhance one’s own ability to survive and create positive healthy relationships whether in love, family & friendships or in work, business or one’s career? Relationships can be hard and life itself IS challenging. Why not arm yourself with the knowledge and breakthroughs that have been made about the mind, mental reactions & interpersonal relationships, so that one has better awareness and control over themselves and life in general. Learn where painful experiences are “stored” and how they can unknowingly affect us. You will also find out how one can “erase” those past painful experiences so that one is free to move forward without being tripped up by the past. Learn too, about what can lead some people to become “toxic” personalities and how to identify those traits in others so you won’t be tripped up trusting the wrong person. Our free Meet-ups occur in a safe environment where one can learn, without fear of judgment or criticism, and without the recommendation of harmful mental techniques or therapies, just how YOU can get yourself onto a happier & more successful path: in love & in life. We look forward to having you join us! This class is sponsored by the Dianetics & Scientology Life Improvement Center of Central Ohio.

Most people use AI like a search box: they type one sentence, hope for the best, and get frustrated when the answer is generic, wrong, or useless. But getting better results from tools like ChatGPT, Claude, Gemini, and other AI systems is not about memorizing magic prompts. It is about learning how to give the AI better context. In this beginner-friendly session, we’ll break down how to make AI dramatically more useful by improving the way you communicate with it. You’ll learn how to give clearer instructions, provide examples, set constraints, ask for better output formats, and use follow-up questions to turn a mediocre answer into a genuinely useful one. We’ll cover practical techniques you can use immediately for work, learning, writing, coding, planning, research, and everyday problem solving. We’ll also touch on why these same ideas show up in more advanced AI systems, including RAG, agents, evaluations, and AI workflows. No technical background required. Bring your curiosity, your questions, and maybe one real task you wish AI was better at helping you with. **What you’ll learn:** * Why “better prompting” is really about better context * How to structure requests so AI gives more useful answers * How to use examples, constraints, and output formats * How to iterate when the first answer is not good enough * How these skills connect to more advanced AI workflows This meetup is for anyone who wants to move beyond basic ChatGPT usage and start getting more practical value out of AI. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.
