This ebook constitutes the joint refereed lawsuits of the 4th overseas Workshop on Approximation Algorithms for Optimization difficulties, APPROX 2001 and of the fifth foreign Workshop on Ranomization and Approximation innovations in machine technological know-how, RANDOM 2001, held in Berkeley, California, united states in August 2001. The 26 revised complete papers offered have been conscientiously reviewed and chosen from a complete of fifty four submissions. one of the matters addressed are layout and research of approximation algorithms, inapproximability effects, online difficulties, randomization, de-randomization, average-case research, approximation periods, randomized complexity concept, scheduling, routing, coloring, partitioning, packing, masking, computational geometry, community layout, and purposes in a variety of fields.

Common codes successfully compress sequences generated via desk bound and ergodic assets with unknown data, they usually have been initially designed for lossless info compression. meanwhile, it used to be learned that they are often used for fixing vital difficulties of prediction and statistical research of time sequence, and this publication describes contemporary ends up in this quarter.

An interesting point is that while a penalty vector is kept non-negative during the execution of an algorithm, a profit vector is expected to be non-positive when the subtraction phase is over. This means, in primal-dual terms, that in the maximization case the dual solution is initially not feasible, and that it becomes feasible at the end of the algorithm. The negative coordinates of the profit vector correspond to the non-tight constraints. In the interval scheduling problem we are given a set of activities, each requiring the utilization of a given resource.
