Aspect-oriented linearizability proofs

Soham Chakraborty ; Thomas A. Henzinger ; Ali Sezgin ; Viktor Vafeiadis.

Linearizability of concurrent data structures is usually proved by monolithic simulation arguments relying on the identification of the so-called linearization points. Regrettably, such proofs, whether manual or automatic, are often complicated and scale poorly to advanced non-blocking concurrency&nbsp;[&hellip;]

Edit Distance for Pushdown Automata

Krishnendu Chatterjee ; Thomas A. Henzinger ; Rasmus Ibsen-Jensen ; Jan Otop.

The edit distance between two words $w_1, w_2$ is the minimal number of word operations (letter insertions, deletions, and substitutions) necessary to transform $w_1$ to $w_2$. The edit distance generalizes to languages $\mathcal{L}_1, \mathcal{L}_2$, where the edit distance from $\mathcal{L}_1$ to&nbsp;[&hellip;]
