2019年7月9日 · We provide an $O(n \log n)$ algorithm computing the linear maximum induced matching width of a tree and an optimal layout.

mmpretrain rc7 版本，调用ImageClassificationInferencer，会出现 no attribute ' show_progress ' 和 unexpected keyword argument show 的 error. 解决方案：更换mmpretrain版本. # mim install -e ".[multimodal]" . 为什么需要config？ __base__：这是openmmlab2.0以后才有的参数，用于 继承 已有config变量，这样就可以做到将一些通用的config参数放到公共位置，让所有的config去继承，做到参数复用.

2023年10月24日 · To date, the only graph class with unbounded linear MIM-width, whose linear MIM-width can be computed in polynomial time, is the trees. In this follow-up, we show that for any tree $T$ with linear MIM-width $k$, the linear MIM-width of its square $T^2$ always lies between $k$ and $2k$, and that these bounds are tight for all $k$.

2019年9月12日 · In this paper we give an \(O(n \log n)\) algorithm computing the linear MIM-width of an n-node tree. This is the first graph class of linear MIM-width larger than 1 having a polynomial-time algorithm computing linear MIM-width and thus constitutes an important step towards a better understanding of this parameter.

Motivated by applications in communication networks of the diameter-constrained minimum spanning tree problem, we consider the delay-constrained minimum shortest path tree (DcMSPT) problem. Specifically, given a weighted graph G = (V, E; w, c) and a ...

We provide an O(nlogn) algorithm computing the linear maximum induced matching width of a tree and an optimal layout. 1 Introduction

2019年7月9日 · We provide an $O(n \log n)$ algorithm computing the linear maximum induced matching width of a tree and an optimal layout. A decision tree corresponding to the case analysis of Proposition 1

maximum induced matching width of a tree and an optimal layout. Keywords: Width parameters · Exact algorithms · Linear MIM-width · Acyclic graphs 1 Introduction The study of structural graph width parameters like tree-width, clique-width and rank-width has been ongoing for a long time, and their algorithmic use has

2019年9月12日 · Motivated by the successful story on algorithmic applications of intersection graphs using a graph width parameter called mim-width, we introduce its directed analogue called `bi-mim-width' and...

We introduce a logic called distance neighborhood logic with acyclicity and connectivity con-straints (A&C DN for short) which extends existential MSO1 with predicates for querying neigh-borhoods of vertex sets in various powers of a graph and …
