Art Walks and Tours

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.

**Let’s kick off our very first CBUS Maker Meetup!** Whether you are looking to carve out dedicated creative time, wanting to get a lingering project across the finish line, or just looking to chat with fellow local makers—this is the space for you. 🧵 **What to Bring** Bring any art or craft project you are currently working on, as long as it is portable and quiet. Think: * **Yarn & Thread:** Knitting, crochet, embroidery, cross-stitch, hand-sewing, mending. * **Paper & Sketching:** Sketchbooks, adult coloring books, watercolors, bullet journaling. * **Digital:** Tablets, iPad drawing, laptop writing/design. * *Please note: Because we are meeting in a shared public space, no power tools, sewing machines, or high-odor materials (like strong solvents or spray glues), please!* **📍 Where to Find Us** * We will be meeting at **Columbus Metropolitan Library - Karl Road Branch** in **Meeting Room 1**. Room is reserved under **CBUS Maker Meetup.** **⏱️ Timeline** * **1:00 PM:** Arrive, grab a seat, get settled, and do a quick round of introductions so we can see what everyone is working on. * **1:15 PM - 3:00 PM:** Open maker time! Chat, craft, relax, and swap creative ideas. **⚠️ A Note on RSVPs** Space for this first meetup is strictly limited to 10 spots. If your plans change and you can no longer attend, please update your RSVP to "Not Going" as soon as possible so someone on the waitlist can grab your spot. We ask that you try to give at least 48 hours' notice if you need to cancel. *** **We can't wait to meet you and see what you're making! All skill levels welcome.**

Let’s meet and wander the galleries! General admission on Sundays is free.

**Not everyone will come. That is exactly why you should.** **Two for Tuesdays** is for the people who actually want to get out and do something instead of just talking about it. We’re kicking off the night with a one-hour social walk before Duckpin Social. **Expect a laid-back** But an Intentional 1 hour walk (2-3 miles), good people, and a better way to spend your Tuesday than staying home and doing the same thing you always do. **If the weather does not cooperate, we’ll move indoors.** **This is a paid event.** A small contribution helps keeps events sustainable and ensures those **who RSVP actually show up.** Payment **Link Found in comments** or you can pay on Venmo, Paypal, @WiseUnlimitedLLC or Cashapp $WiseUnlimitedLLC. Walk RSVP **$2** Walk / DuckPin Social **$5** Walk / DuckPin Social + 1 game of duckpin **$12** Please be sure **to Put Event and Event Date** in the note when paying RSVP Fee

Welcome to the Art School - 20's & 30's artists Meetup group! This is a community for young artists who are passionate about exploring different mediums and techniques in the world of art. Whether you're a painter, sculptor, photographer, or mixed media artist, this group is the perfect place to connect with like-minded individuals, have a space to work on your craft, and showcase your work. Let's inspire and support each other on our artistic journeys! Whether you're a novice or a seasoned artist, all skill levels are welcome. Join us and unleash your creativity! Afterwards, we will have time to work on our individual art projects, hang out, and if anyone is interested in feedback on their work, there will be time for that as well.

Join us this Thursday 6:30 pm at the Westerville Veterans Memorial for two loops around the Westerville Sports Complex fields. This 1 mile loop is a flat fully paved trail that straddles Alum Creek. Join us for a beautiful evening hike together!
