Weighted Logics for Unranked Tree Automata
: We define a weighted monadic second order logic for unranked trees and the concept of weighted unranked tree automata, and we investigate the expressive power of these two conce...

Weighted Picture Automata and Weighted Logics
The theory of two-dimensional languages, generalizing formal string languages, was motivated by problems arising from image processing and models of parallel computing. Weighted au...

Quantitative Languages
Quantitative generalizations of classical languages, which assign to each word a real number instead of a boolean value, have applications in modeling resource-constrained computat...

Weighted O-Minimal Hybrid Systems Are More Decidable Than Weighted Timed Automata!
Abstract. We consider weighted o-minimal hybrid systems, which extend classical o-minimal hybrid systems with cost functions. These cost functions are “observer variables” whic...
