In this paper we introduce two general techniques for the design and analysis of approximation algorithms for NP-hard scheduling problems in which the objective is to minimize the weighted sum of the ...

Abstract: Cloud computing is now widely used in all major industries. This transformative technology allows users to access the resources they need through a pay-as-you-go model, providing an ...

The paper considers a project scheduling problem in weighted directed graphs in which arcs represent operations while nodes are identified with starting and finishing endpoints of the operations; arc ...
