Evaluating Program Repair with Semantic-Preserving Transformations: A Naturalness Assessment

1 code implementation19 Feb 2024 Thanh Le-Cong, Dat Nguyen, Bach Le, Toby Murray

In this paper, we investigate the naturalness of semantic-preserving transformations and their impacts on the evaluation of NPR.

Symbol Correctness in Deep Neural Networks Containing Symbolic Layers

no code implementations6 Feb 2024 Aaron Bembenek, Toby Murray

To handle AI tasks that combine perception and logical reasoning, recent work introduces Neurosymbolic Deep Neural Networks (NS-DNNs), which contain -- in addition to traditional neural layers -- symbolic layers: symbolic expressions (e. g., SAT formulas, logic programs) that are evaluated by symbolic solvers during inference.

State Selection Algorithms and Their Impact on The Performance of Stateful Network Protocol Fuzzing

no code implementations24 Dec 2021 Dongge Liu, Van-Thuan Pham, Gidon Ernst, Toby Murray, Benjamin I. P. Rubinstein

In this work, we evaluate an extensive set of state selection algorithms on the same fuzzing platform that is AFLNet, a state-of-the-art fuzzer for network servers.

Legion: Best-First Concolic Testing

no code implementations15 Feb 2020 Dongge Liu, Gidon Ernst, Toby Murray, Benjamin I. P. Rubinstein

Legion incorporates a form of directed fuzzing that we call approximate path-preserving fuzzing (APPFuzzing) to investigate program states selected by MCTS.

Empirically Analyzing Ethereum's Gas Mechanism

1 code implementation2 May 2019 Renlord Yang, Toby Murray, Paul Rimba, Udaya Parampalli

Finally, our results suggest that under the current Gas cost model, nodes with modest computational resources are disadvantaged compared to their better resourced peers, which we identify as an ongoing threat to node diversity and network decentralization.
