Kayaking and Camping

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.

🚗 **Only about 20 minutes from floating down the river!** This is one of those events you’ll be glad you showed up for. Especially since it **may be one of the last** cookout bonfire party that is held. Cookout, potluck, racing, camping, bonfire, music, games, and late-night hangs — all in one night. Com**e for a few hours or stay** for the whole thing. ## 🍔 Cookout + Potluck — 4:30 PM We’ll be hanging out, grilling, eating, drinking, and socializing before the races start. Please bring something to share **USE "SIGN UP"** so we don’t end up with 14 bags of chips and 9 packs of cookies 😅 **What to bring:** * Chair, BYOB — no glass inside the racetrack, Water or youself even if you leave it in the car, **$15 cash to support the venue** by watching some of the race * Something for the potluck USE **"SIGN UP"** We’ll have a grill and a **generator** available for crockpots, Instant Pots, etc. ## 🏁 Racing Starts — 7:00 PM After the cookout, we’ll head into the stands for the races. Not really into racing? Come for the drinks, stay for the wrecks 🍻 This night includes Late Models, Thunder Cars, Compacts, and a wet & wild Enduro race. Be sure to bring **water balloons to fill up and** throw during the final race 💦🎯 Please support the venue by checking out some of the racing. 💵 **$15 cash will be collected during the cookout.** Please bring exact change or a $20. ## 🏕️ Free Camping — June 5 & 6 Camping is free both nights. No tent? No problem. You can crash **in your car under the stars.** There will be a bonfire, music, games, and late-night hanging out. Please be responsible: **do not drink and drive.** ## 🎯 Other Stuff Happening * Karaoke, Beer pong, Cornhole, Bonfire, Music, Late-night hangout Have a favorite karaoke song? Let me know. ## Important Notes 📸 Photos/videos may be taken and shared on this or other platforms. ⚠️ This is a volunteer-led event. You participate at your own risk. 📵 Cell signal may be spotty, so ask questions ahead of time if needed. Stay for a bit or go all in — just don’t miss this one. **Stop scrolling. Start doing stuff.**
