Walking

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.

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!

**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

Garden to the Max Join the Inniswood Garden Society for their annual meeting and garden reception. Featured speaker, Teresa Woodard, will discuss maximalist gardening Having a maximalist garden is a bold aesthetic choice—yet it also brings vitality back to the earth, in an abundant expression of more. Garden to the Max celebrates gardens across the US that embrace maximalism through joy and wonder, nonstop blooms, and abundant layers 06/07/2026 Time: 2:00 pm - 4:00 pm Days: Sun Inniswood Metro Gardens 940 S Hempstead Rd Westerville, OH, 43081 (614)508-8111 Location Map: Innis House.
