Finding Approximate Palindromes in Strings Quickly and Simply
: Described are two algorithms to find long approximate palindromes in a string, for example a DNA sequence. A simple algorithm requires O(n)space and almost always runs in O(k.n)-...

Generating connected acyclic digraphs uniformly at random
We describe a simple algorithm based on a Markov chain process to generate simply connected acyclic directed graphs over a fixed set of vertices. This algorithm is an extension of...

On the uniform edge-partition of a tree
We study the problem of uniformly partitioning the edge set of a tree with n edges into k connected components, where k ≤ n. The objective is to minimize the ratio of the maximu...

Improved results for directed multicut
We give a simple algorithm for the MINIMUM DIRECTED MULTICUT problem, and show that it gives an Ç´ÔÒµapproximation. This improves on the previous approximation guarantee of Ã...
