A new infeasible interior-point algorithm for linear programming
In this paper we present an infeasible path-following interiorpoint algorithm for solving linear programs using a relaxed notion of the central path, called quasicentral path, as ...

The Core Concept for 0/1 Integer Programming
In this paper we examine an extension of the core concept for the 0/1 Multidimensional Knapsack Problem (MKP) towards general 0/1 Integer Programming (IP) by allowing negative pro...

Linear Time Algorithms for Clustering Problems in Any Dimensions
Abstract. We generalize the k-means algorithm presented by the authors [14] and show that the resulting algorithm can solve a larger class of clustering problems that satisfy certa...

On the Huffman and Alphabetic Tree Problem with General Cost Functions
We study a wide generalization of two classical problems, the Huffman Tree and Alphabetic Tree Problem. We assume that the cost caused by the ith leaf is fi(di), where di is its d...
