Breaking intractability of spanning caterpillar tree problem: A logical approach [PDF]

open access: yesAUT Journal of Mathematics and Computing, 2022
In this paper we pursue a logical approach to prove that the optimisation problem of finding a spanning caterpillar tree in a graph has polynomial algorithm for bounded tree width graphs.

A Functional (Monadic) Second-Order Theory of Infinite Trees [PDF]

open access: yesLogical Methods in Computer Science, 2020
This paper presents a complete axiomatization of Monadic Second-Order Logic (MSO) over infinite trees. MSO on infinite trees is a rich system, and its decidability ("Rabin's Tree Theorem") is one of the most powerful known results concerning the ...

An expressive completeness theorem for coalgebraic modal mu-calculi [PDF]

open access: yesLogical Methods in Computer Science, 2017
Generalizing standard monadic second-order logic for Kripke models, we introduce monadic second-order logic interpreted over coalgebras for an arbitrary set functor. We then consider invariance under behavioral equivalence of MSO-formulas.

Local Normal Forms for First-Order Logic with Applications to Games and Automata [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 1999
Building on work of Gaifman [Gai82] it is shown that every first-order formula is logically equivalent to a formula of the form ∃ x 1,...,x l, ∀ y, φ where φ is r-local around y, i.e.

Regular Cost Functions, Part I: Logic and Algebra over Words [PDF]

open access: yesLogical Methods in Computer Science, 2013
The theory of regular cost functions is a quantitative extension to the classical notion of regularity. A cost function associates to each input a non-negative integer value (or infinity), as opposed to languages which only associate to each input the ...

On the Expressive Power of 2-Stack Visibly Pushdown Automata [PDF]

open access: yesLogical Methods in Computer Science, 2008
Visibly pushdown automata are input-driven pushdown automata that recognize some non-regular context-free languages while preserving the nice closure and decidability properties of finite automata. Visibly pushdown automata with multiple stacks have been

Preferred Attribute Elicitation (PAE) in the Sensory Descriptive Analysis of Foods: A Deep Comprehensive Review of the Method Steps, Application, Challenges, and Trends. [PDF]

open access: yesCompr Rev Food Sci Food Saf
ABSTRACT Descriptive analysis (DA) is the gold standard for sensory profiling due to its robustness and reliability. However, its high cost, time demand, and labor intensity limit routine applications in the food industry. Rapid Sensory Profiling Techniques (RSPTs) have emerged as faster, less resource‐intensive alternatives to address these challenges.

Complete Axiomatizations of Fragments of Monadic Second-Order Logic on Finite Trees [PDF]

open access: yesLogical Methods in Computer Science, 2012
We consider a specific class of tree structures that can represent basic structures in linguistics and computer science such as XML documents, parse trees, and treebanks, namely, finite node-labeled sibling-ordered trees.

The monadic second-order logic of graphs XVI : Canonical graph decompositions [PDF]

open access: yesLogical Methods in Computer Science, 2006
This article establishes that the split decomposition of graphs introduced by Cunnigham, is definable in Monadic Second-Order Logic.This result is actually an instance of a more general result covering canonical graph decompositions like the modular ...

Monadic second-order definable graph orderings [PDF]

open access: yesLogical Methods in Computer Science, 2014
We study the question of whether, for a given class of finite graphs, one can define, for each graph of the class, a linear ordering in monadic second-order logic, possibly with the help of monadic parameters.
