<p class="description">Erwin is a programming consultant who works on the design & implementation of mathematical programming, optimization, and data-science applications. Even though he can't blog about projects he's working on, he shares lots of his technical notes & code solutions for others to learn from.</p>
Yet Another Math Programming Consultant is an exceptional technical blog by Erwin Kalvelagen, a veteran operations research consultant. The blog dives deep into mathematical programming, optimization modeling, and operations research with remarkable clarity. What sets it apart is the practical, hands-on approach"posts frequently include working code examples in GAMS, Python, and other languages, along with detailed explanations of modeling techniques. The content covers linear programming, mixed-integer programming, constraint programming, and various solver comparisons. While the highly technical nature means it's best suited for practitioners and advanced students rather than beginners, those in the optimization space will find it an invaluable resource. The consistent quality and depth of analysis over many years makes this a go-to reference for anyone serious about mathematical optimization.
