Verifolio is a portfolio software verification tool.

Given a verification task and a verification property, it tries to predict the best tool from a predefined set of black-box verification tools. Our portfolio is based on high-level software metrics, variable roles and loop patterns. We have evaluated Verifolio on data from the International Competition on Software Verification (SV-COMP), where our portfolio outperforms any of the participating standalone verifiers.

NEW: Students interested in formal methods and machine learning should check related master’s thesis and semester project topics.

Winter School on Verification

The Austrian Society for Rigorous Systems Engineering (ARiSE) and the Vienna Center for Logic and Algorithms (VCLA) are organizing a joint winter school on verification at Vienna University of Technology from 6-10 February 2012. Apart from ARiSE/VCLA students, the school will be open to outside students. Details are available from the VCLA website.

CfP: Workshop on Exploiting Concurrency Efficiently and Correctly (EC^2 2010)

The annual Workshop on Exploiting Concurrency Efficiently and Correctly (EC2) is a forum that brings together researchers working on formal methods for concurrency, and those working on advanced parallel applications. Its goal is to stimulate incubation of ideas leading to future concurrent system design an verification tools that are essential in the multi-core era.
