Abstract
The calculation of GVT has been a requirement to identify fossilized state and event space during Time Warp simulations. This paper outlines methods that use observations of past behavior to estimate future behavior for the purposes of fossil reclamation. More precisely, predictions of future rollback behavior are used to determine a probability that a particular item of saved state or event information is no longer needed. This probability is compared against a user-defined risk factor to decide if the space can be reclaimed and reused. This method is called optimistic fossil collection and it is fully distributed, not requiring the global estimate of GVT for operation.
