Digging for Decision Trees: A Case Study in Strategy Sampling and Learning
Carlos E. Budde, Pedro R. D'Argenio, Arnd Hartmanns
We introduce a formal model of transportation in an open-pit mine for the purpose of optimising the mine's operations. The model is a network of Markov automata (MA); the optimisat…
Forecasting the risk of software choices: A model to foretell security vulnerabilities from library dependencies and source code evolution
Carlos E. Budde, Ranindya Paramitha, Fabio Massacci
Software security mainly studies vulnerability detection: is my code vulnerable today? This hinders risk estimation, so new approaches are emerging to forecast the occurrence of fu…
Transient Evaluation of Non-Markovian Models by Stochastic State Classes and Simulation
Gabriel Dengler, Laura Carnevali, Carlos E. Budde +1
Non-Markovian models have great expressive power, at the cost of complex analysis of the stochastic process. The method of Stochastic State Classes (SSCs) derives closed-form analy…
Vulnerability anti-patterns in Solidity: Increasing smart contracts security by reducing false alarms
Tommaso Oss, Carlos E. Budde
Turing completeness has made Ethereum smart contracts attractive to blockchain developers and attackers alike. To increase code security, many tools can now spot most known vulnera…
Tools at the Frontiers of Quantitative Verification
Roman Andriushchenko, Alexander Bork, Carlos E. Budde +20
The analysis of formal models that include quantitative aspects such as timing or probabilistic choices is performed by quantitative verification tools. Broad and mature tool suppo…
