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.
