Expressiveness and Closure Properties for Quantitative Languages

Krishnendu Chatterjee ; Laurent Doyen ; Thomas A Henzinger.

Weighted automata are nondeterministic automata with numerical weights on transitions. They can define quantitative languages~$L$ that assign to each word~$w$ a real number~$L(w)$. In the case of infinite words, the value of a run is naturally computed as the maximum, limsup, liminf, limit-average,&nbsp;[&hellip;]

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;]
