Optimizing Generation of Object Graphs in Java PathFinder
Java PathFinder (JPF) is a popular model checker for Java programs. JPF was used to generate object graphs as test inputs for object-oriented programs. Specifically, JPF was used...

The Complexity of Transformation-Based Join Enumeration
Query optimizers that explore a search space exhaustively using transformation rules usually apply all possible rules on each alternative, and stop when no new information is prod...

Q-learning and enhanced policy iteration in discounted dynamic programming
We consider the classical finite-state discounted Markovian decision problem, and we introduce a new policy iteration-like algorithm for finding the optimal state costs or Q-facto...

Automatic Tuning of Two-Level Caches to Embedded Applications
The power consumed by the memory hierarchy of a microprocessor can contribute to as much as 50% of the total microprocessor system power, and is thus a good candidate for optimiza...
