Mathematical programming (optimization) has so many useful applications and I am very pleased to see this classical book on the topic available online. Unfortunately because it has been written a while ago it doesn't cover algebraic modeling languages and examples are in Excel which is not an adequate optimization or teaching tool (even XKCD has something to say about it in his webcomic https://xkcd.com/1667/ https://xkcd.com/1667/).
