Parity Games with Weights

Sven Schewe ; Alexander Weinert ; Martin Zimmermann.

Quantitative extensions of parity games have recently attracted significant interest. These extensions include parity games with energy and payoff conditions as well as finitary parity games and their generalization to parity games with costs. Finitary parity games enjoy a special status among these&nbsp;[&hellip;]

A Bit of Nondeterminism Makes Pushdown Automata Expressive and Succinct

Shibashis Guha ; Ismaël Jecker ; Karoliina Lehtinen ; Martin Zimmermann.

We study the expressiveness and succinctness of history-deterministic pushdown automata (HD-PDA) over finite words, that is, pushdown automata whose nondeterminism can be resolved based on the run constructed so far, but independently of the remainder of the input word. These are also known as&nbsp;[&hellip;]
