Approximating the ,-low-density Valueical inputs, and the analysis yields bounds that better reflect the behaviour of algorithms in practice..One of the most popular models for polygonal curves and objects is .-low-density. To select the most efficient algorithm for a certain input, one often needs to approximate the .-low-density valu

Linear Time Algorithms for NP-Hard Problems Restricted to , Graphsgraphs that can be uniquely represented by a rooted tree where the leaves of the tree correspond to the vertices of the graph. As a generalization, . graphs are precisely those graphs that can be uniquely represented by a particular rooted directed acyclic graph (called galled-tree)..We consider her

Polynomial Turing Compressions for Some Graph Problems Parameterized by Modular-Widthuch that a polynomial in the input parameter bounds each query. Meanwhile, a polynomial (many-one) compression (PC) can be regarded as a restricted variant of PTC where the machine can query the oracle exactly once and must output the same answer as the oracle. Bodlaender et al. (ICALP 2008) and For

List 3-Coloring on Comb-Convex and Caterpillar-Convex Bipartite Graphso that each vertex receives a color from its own list and no two neighboring vertices receive the same color. The decision version of the problem . is NP-complete even for bipartite graphs, and its complexity on comb-convex bipartite graphs has been an open problem. We give a polynomial-time algorit
