A Polynomial-Time Approximation Scheme for Weighted Planar Graph TSP
Given a planar graph on n nodes with costs weights on its edges, de ne the distance between nodes i and j as the length of the shortest path between i and j. Consider this as an i...

A Fast General Methodology for Information - Theoretically Optimal Encodings of Graphs
We propose a fast methodology for encoding graphs with information-theoretically minimum numbers of bits. Specifically, a graph with property π is called a π-graph. If π satis...

In-Place Suffix Sorting
Given string T = T[1, . . . , n], the suffix sorting problem is to lexicographically sort the suffixes T[i, . . . , n] for all i. This problem is central to the construction of suf...
