Succinct Data Structures for Baxter Permutation and Related Families
Sankardeep Chakraborty, Seungbum Jo, Geunho Kim +1
A permutation is a Baxter permutation if and only if it does not contain either of the patterns and . Baxter permutations are one of the m…

A Simple Representation of Tree Covering Utilizing Balanced Parentheses and Efficient Implementation of Average-Case Optimal RMQs
Kou Hamada, Sankardeep Chakraborty, Seungbum Jo +3
Tree covering is a technique for decomposing a tree into smaller-sized trees with desirable properties, and has been employed in various succinct data structures. However, signific…

Succinct Data Structure for Chordal Graphs with Bounded Vertex Leafage
Girish Balakrishnan, Sankardeep Chakraborty, N S Narayanaswamy +1
We improve the worst-case information theoretic lower bound of Munro and Wu (ISAAC 2018) for vertex unlabeled chordal graphs when vertex leafage is bounded and leafage is unbou…
