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! Фори, Ники, Явор

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!
