Improving First-order Model Searching by Propositional Reasoning and Lemma Learning
The finite model generation problem in the first-order logic is a generalization of the propositional satisfiability (SAT) problem. An essential algorithm for solving the proble...

On the Power of Clause-Learning SAT Solvers with Restarts
In this work, we improve on existing work that studied the relationship between the proof system of modern SAT solvers and general resolution. Previous contributions such as those ...

On the Hardness and Easiness of Random 4-SAT Formulas
Assuming 3-SAT formulas are hard to refute with high probability, Feige showed approximation hardness results, among others for the max bipartite clique. We extend this result in t...

Visualizing the Internal Structure of SAT Instances (Preliminary Report)
Modern algorithms for the SAT problem reveal an almost tractable behavior on “real-world” instances. This is frequently contributed to the fact that these instances possess an ...
