A Reinforcement Learning based Reset Policy for CDCL SAT Solvers

no code implementations4 Apr 2024 Chunxiao Li, Charlie Liu, Jonathan Chung, Zhengyang Lu, Piyush Jha, Vijay Ganesh

In most solvers, variable activities are preserved across restart boundaries, resulting in solvers continuing to search parts of the assignment tree that are not far from the one immediately prior to a restart.

Layered and Staged Monte Carlo Tree Search for SMT Strategy Synthesis

1 code implementation30 Jan 2024 Zhengyang Lu, Stefan Siemer, Piyush Jha, Joel Day, Florin Manea, Vijay Ganesh

Our method treats strategy synthesis as a sequential decision-making process, whose search tree corresponds to the strategy space, and employs MCTS to navigate this vast search space.

CGDTest: A Constrained Gradient Descent Algorithm for Testing Neural Networks

no code implementations4 Apr 2023 Vineel Nagisetty, Laura Graves, Guanting Pan, Piyush Jha, Vijay Ganesh

This functionality sets CGDTest apart from other similar DNN testing tools since it allows users to specify logical constraints to test DNNs not only for $\ell_p$ ball-based adversarial robustness but, more importantly, includes richer properties such as disguised and flow adversarial constraints, as well as adversarial robustness in the NLP domain.
