Abstract
A system and method for generating suggestions to a user using simulated annealing is disclosed. The system includes a user activity processing unit, a recommendation engine, a ranking engine and a simulated annealing engine. The user activity processing unit receives user activities and generates user interests. The simulated annealing engine generates a temperature to control how far to stray from highly relevant suggestions. The recommendation engine generates a query for content and generates at least one suggestion for the user from received content. The ranking engine ranks the at least one suggestion based on a recency of user interests, frequency of actions associated with the user interests and social affinity of the user to other users that generated any of the at least one suggestions.
