Calculating lower bounds for caching problems
We present a general method for computing lower bounds for various caching problems. We apply the method to two well known problems, companion caching and weighted caching. For we...

Robust Bayesian reinforcement learning through tight lower bounds
In the Bayesian approach to sequential decision making, exact calculation of the (subjective) utility is intractable. This extends to most special cases of interest, such as reinfo...

Tightening the Bounds on Feasible Preemption Points
Caches have become invaluable for higher-end architectures to hide, in part, the increasing gap between processor speed and memory access times. While the effect of caches on timi...

Cache-Oblivious Comparison-Based Algorithms on Multisets
Abstract. We study three comparison-based problems related to multisets in the cache-oblivious model: Duplicate elimination, multisorting and finding the most frequent element (th...

Designing an A* Algorithm for Calculating Edit Distance between Rooted-Unordered Trees
Tree structures are useful for describing and analyzing biological objects and processes. Consequently, there is a need to design metrics and algorithms to compare trees. A natura...
