Analysis of the Multiplicity Matching Parameter in Suffix Trees
Description Abstract We analyze one redundant aspect of the encoder for the Lempel-Ziv '77 data compression algorithm. We prove that the number of pointers into the LZ'77 database asymptotically...

Strongly Chordal Graphs and Related Structures
Description Strongly chordal graphs were introduced by Farber in 1983, as a restricted class of graphs for which the weighted dominating set problem can be solved in polynomial time; the problem is NP...

Fractal Sets and Boundary Theory
Description We discuss how the boundary concept can be used to describe fractal sets. Two examples illustrate this: 1. Polynomial endomorphisms of C2 and their Julia sets; 2. Self-similar fractals...
