About

OR Exchange was designed as a question-and-answer site for the operations research and analytics community. Unfortunately, the platform on which it runs has low resistance to spam, and in recent years spammers managed to overwhelm its minimal defenses. As a result, registration and posting have been disabled, and there is no plan to reactivate them.

You are free to search and read the accumulated content, but you will not be able to post new questions. If you are looking for an alternative Q&A site, you might consider Operations Research Stack Exchange.

OR-Exchange! Your site for questions, answers, and announcements about operations research.
