An Optimal Multiple-Class Encoding Scheme for a Graph of Bounded Hadwiger Number

Hsueh-I Lu

Since Jacobson [FOCS89] initiated the investigation of succinct graph encodings 35 years ago, there has been a long list of results on balancing the generality of the class, the sp…

A Simple 2-Approximation for Maximum-Leaf Spanning Tree

I-Cheng Liao, Hsueh-I Lu

For an -edge connected simple graph , finding a spanning tree of with the maximum number of leaves is MAXSNP-complete. The problem remains NP-complete even if is plan…

Improved Algorithms for Recognizing Perfect Graphs and Finding Shortest Odd and Even Holes

Yung-Chung Chiu, Kai-Yuan Lai, Hsueh-I Lu

Various classes of induced subgraphs are involved in the deepest results of graph theory and graph algorithms. A prominent example concerns the {\em perfection} of that the chr…

Finding a Shortest Even Hole in Polynomial Time

Hou-Teng Cheong, Hsueh-I Lu

An even (respectively, odd) hole in a graph is an induced cycle with even (respectively, odd) length that is at least four. Bienstock [DM 1991 and 1992] proved that detecting an ev…

Three-in-a-Tree in Near Linear Time

Kai-Yuan Lai, Hsueh-I Lu, Mikkel Thorup

The three-in-a-tree problem is to determine if a simple undirected graph contains an induced subgraph which is a tree connecting three given vertices. Based on a beautiful characte…
