Anytime Dynamic A*: An Anytime, Replanning Algorithm

We present a graph-based planning and replanning algorithm able to produce bounded suboptimal solutions in an anytime fashion. Our algorithm tunes the quality of its solution based on available search time, at every step reusing previous search efforts. When updated information regarding the underlying graph is received, the algorithm incrementally repairs its previous solution. The result is a...

Anytime Truncated D* : Anytime Replanning with Truncation

Incremental heuristic searches reuse their previous search efforts to speed up the current search. Anytime search algorithms iteratively tune the solutions based on available search time. Anytime D* (AD*) is an incremental anytime search algorithm that combines these two approaches. AD* uses an inflated heuristic to produce bounded suboptimal solutions and improves the solution by iteratively d...

Apocalypse soon?

When the Lord smote the Philistines with emerods in their secret parts he left it to historians to debate the nature of this lethal affliction. Literally translated, emerods are haemorrhoids, but it is surely unlikely that so hardy a race would have succumbed to an epidemic of piles. Scholarly opinion seems to concur that the emerods were buboes in the groin, one of the agonising manifestations...

No heroic measures: how soon is too soon to stop?

Persistent HIV infection in newborns: how soon is soon enough?

Over the last few years, attention has been drawn to efforts that seek to develop a cure for HIV infection. Investigators and scientists seek to completely eradicate HIV infection (called by some a sterilizing cure), or allow patients to interrupt antiretroviral therapy (ART) without the risk of viral rebound, viral transmission, or progressive disease (known as a functional cure). This wave of...
