On basis-exchange properties for matroids
We give a counterexample to a conjecture by Wild about binary matroids. We connect two equivalent lines of research in matroid theory: a simple type of basis-exchange property and ...

A Reachability Predicate for Analyzing Low-Level Software
Reasoning about heap-allocated data structures such as linked lists and arrays is challenging. The reachability predicate has proved to be useful for reasoning about the heap in ty...

Fundamental Properties of the Core Matching Functions for Information Retrieval
Traditional benchmarking methods for information retrieval (IR) are based on experimental performance evaluation. Although the metrics precision and recall can measure the perform...

Timed Diagnostics for Reachability Properties
We consider the problem of computing concrete diagnostics for timed automata and reachability properties. Concrete means containing information both about the discrete state change...
