Springer Tracts in Modern Physicsthis result to develop the first virtualized services placement algorithm that accounts for dynamic changes. Our tri-criteria approximation algorithms provide constant approximation factors with respect to the overall performance and size constraints, and logarithmic approximation factors with respect to capacity constraints.

Improved Approximation Algorithms for Minimum Power Covering Problemsieve ratio 73?/?60, and in addition give a simple efficient combinatorial algorithm with ratio 5?/?4. For all these NP-hard problems the previous best known ratio was 3?/?2. In the related . problem, . should contain a path from every . to some node in .. We obtain ratio 3?/?2 for this NP-hard problem, improving the trivial ratio of 2.

DISPATCH: An Optimally-Competitive Algorithm for Maximum Online Perfect Bipartite Matching with i.i.lable. The preferred worker is determined based on an optimal solution to a fractional transportation problem. If the preferred worker is not available, . randomly selects a worker from the available workers. We show that . maintains a uniform distribution over the workers even when the distribution over the job types is non-uniform.
