An estimation algorithm for a query is a probabilistic algorithm that computes an approximation for the size (number of tuples) of the query. One class of estimation algorithms us...
In dynamically changing environments a planning system does not have all the required information at the first place and the world state can change, rendering the original plan i...
The management of complexity in large systems is traditionally focused on the modeling and management of classes and hierarchies of classes. In order to improve the compositional ...
This paper is concerned with the complexity of proofs and of searching for proofs in two propositional proof systems: Resolution and Polynomial Calculus (PC). For the former syste...
The evolution of software systems over many years often leads to unnecessarily complex and in exible designs which in turn lead to a huge amount of e ort for enhancements and main...
