On bounded occurrence constraint satisfaction
An approximation algorithm for a constraint satisfaction problem is said to be nontrivial if its performance ratio is strictly superior to the expected performance of the algorith...

Clustering Variable Length Sequences by Eigenvector Decomposition Using HMM
We present a novel clustering method using HMM parameter space and eigenvector decomposition. Unlike the existing methods, our algorithm can cluster both constant and variable leng...

Bounding Preemption Delay within Data Cache Reference Patterns for Real-Time Tasks
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...

Simple Bounded LTL Model Checking
We present a new and very simple translation of the bounded model checking problem which is linear both in the size of the formula and the length of the bound. The resulting CNF-fo...

BDD Variable Ordering for Interacting Finite State Machines
We address the problem of obtaining good variable orderings for the BDD representation of a system of interacting finite state machines (FSMs). Orderings are derived from the comm...
