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.

Hosted by OSU Extension Summer 2026 Food Preservation Workshops Join Shari Gallup from Ohio State University Extension, for a summer food preservation series at the Bryn Du Mansion. Discover how to safely preserve food at home. Learn basic food preservation methods including pressure canning, water bath canning and drying. June 4 - Water Bath Canning July 9 - Pressure Canning August 6 - Drying Fruits and Vegetables We're excited to once again welcome Shari Gallup from The Ohio State University Extension Office to lead a series of Life Local food preservation workshops. These hands-on sessions are designed to help participants learn practical, time-tested techniques for preserving seasonal foods at home. Registration is not yet open but will be available soon. Stay tuned for details on this wonderful series. Time 5:00 p.m. Location Bryn Du Mansion 587 Jones Road, Granville https://www.bryndu.com/public-events
