Protect the Forest

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.

Hi Ladies , Let's Hike Blendon Woods Metro Park . We will meet at the nature center parking lot. Hiking about 4 miles completing the blendon woods loop and the sugarbush trail . Wear appropriate footwear and bring water for hydration .

**How to take control of your subconscious and harness its power!** Join us for an eye-opening lecture where the speaker will break down complex ideas in a clear and practical way. You’ll gain insights into: ✅ The true definition of the subconscious ✅ How it generates unwanted emotions ✅ Its real purpose and function ✅ What determines the pressure it exerts on you And the most important topic: **How do you take control of your subconscious!** But this isn’t just another lecture where you sit and listen passively. It’s interactive and engaging—you can ask questions at any time. 📅 Reserve your spot now! Seats are limited, so don’t wait too long to sign up. Location: 1266 Dublin Rd, Columbus, OH 43215 Hosted by the Hubbard Dianetics Foundation

Jimmy V's Grill & Pub in Grandview Heights. You are responsible for your own meal/drinks. We usually don't have any agenda other than eat, drink and talk. :) If the weather is nice we will be on the back patio, otherwise we are in the cigar room. This group has been meeting every Tuesday evening for over a decade. Many attendees do not RSVP on meetup. Please don't let the small number here discourage you. Anyone/everyone is welcome to come. We'd love to have you join us. COTA bus #5 comes to W. 5th and Wyandotte Rd. And it's a minute walk to the restaurant.

NOTICE CHANGE OF LOCATION. WE WILL BE MEETING AT THE SHARON WOODS METRO PARK - THIS MONTH ONLY. Sharon Woods Metro Park, 6911 Cleveland Ave, Westerville, OH 43081 Enter the park from Cleveland Avenue and stay on the main park drive until it dead-ends into a turn around parking lot. We will meet at the Schrock Lake Shelter just off this parking area to the right. We will be taking a Guided Walk with access very near the shelter, on the Edward S Thomas trail, an ADA flat, hard-packed gravel surface trail. This walk will be led by Carrie Keller, Outdoor Naturalist at the park, and Megan Richley, Inclusion Coordinator for the Metro Parks. Wear sneakers or other shoes covering the entire foot. Sandals or flip-flops are ill advised. Sighted guides will be available. Target audience for this group is persons who are visually impaired, especially those who have experienced recent loss, however, all are welcome, including family members and supports. Light refreshments will be served. There will not be a Conference Call option for this meeting.

Hi ladies. Let's hike the Edward Thomas, Spring Creek, and a little multi-purpose trail - approximately 4 miles so please wear your shoe of choice. Please bring a water bottle as needed and appropriate shoes. Meet in the Maple Grove Picnic area.
