Does this apply for secret challenges too? For example, say a regular challenge where the relation #22 is floating around. Are you allowed to offer a secret challenge with relation #22 or this not allowed? Thanks, --Jon From: http://www.research.att.com/~pamela/faq.html What is a feature? In a software system, a feature is an increment of functionality, usually with a coherent purpose. If a system description is organized by features, then it probably takes the form B + F1 + F2 + F3 . . ., where B is a base description, each Fi is a feature module, and + denotes some feature-composition operation. What is a feature interaction? A feature interaction is some way in which a feature or features modify or influence another feature in defining overall system behavior. What is the feature-interaction problem? Historically, developers of telecommunication software have had no effective means of understanding and managing feature interactions. As a result, feature interactions have been a notorious source of runaway complexity, software bugs, cost and schedule overruns, and unfortunate user experiences. Developers of other software systems are beginning to realize that they, too, have a feature-interaction problem. ========================= What are our features?
