A new method is proposed for online handwriting recognition of Kanji characters. The method employs substroke HMM as minimum units to constitute Japanese Kanji characters …
We consider questions that arise from the intersection between the areas of polynomial-time approximation algorithms, subexponential-time algorithms, and fixed-parameter tractable …
Structural graph parameters, such as treewidth, pathwidth, and clique-width, are a central topic of study in parameterized complexity. A main aim of research in this area is to …
Given a graph $ G $ and an integer $ k $, Max Min FVS asks whether there exists a minimal set of vertices of size at least $ k $ whose deletion destroys all cycles. We present several …

The parameterized complexity of problems is often studied with respect to the size of their optimal solutions. However, for a maximization problem, the size of the optimal solution can …

For any $\varepsilon> 0$, we give a polynomial-time $ n^\varepsilon $-approximation algorithm for Max Independent Set in graphs of bounded twin-width given with an $ O (1) …
In this paper, we develop new tools and connections for exponential time approximation. In this setting, we are given a problem instance and an integer r> 1 r> 1, and the goal is to …
This survey investigates the field of moderate exponential-time algorithms for NP-hard scheduling problems, ie, exact algorithms whose worst-case time complexity is moderately …
In this work, we focus on several completion problems for subclasses of chordal graphs: Minimum Fill-In, Interval Completion, Proper Interval Completion, Trivially Perfect …
