In July 2016, MicroSoft released an update to Office 365 which prevents OpenSolver from loading unless the. OpenSolver not loading – July 2016 Office update (no error message) Common Software ProblemsĮxcel can have problems dealing with add-ons. If you still have a modelling question (e.g., how do I express this requirement using the rules for a linear program), please ask it on. (Thanks to Stu Mitchell of PuLP fame for pointing out this resource.) The NEOS guide is also a great resource. The AIMMS folks have a great online chapter describing how to take non-linear requirements ( local copy of pdf) and model them using linear programming. (OpenSolver uses CBC by default to solve these linear programmes.) Check out this Wiki page on linear programming. However, most of the time you want to build these “linear programming” models (and avoid non-linear models) because these are easier and more reliable to solve using packages such as OpenSolver. Writing optimisation models that only use linear mathematical equations and inequalities is not easy. However, if you still have a question, please post it below. We hope that most of your questions will be answered on the Using OpenSolver page.
