As more and more cloud services are provided on the web, composite services will increase exponentially. How to select the optimal services for a given composite service is a important problem and is NP-Hard. This paper proposes a multi-objective service selection algorithm based on MOACS(Multi-Objective Ant Colony System) optimization algorithm for this problem. In this problem, two objectives are...
Reselection of composition service is one of the core research issues in the service computing field. Most of the existin-g researches for this problem are based on the assumption that the tasks involved are independent. However, in practical scenar-ios, the QoS of some candidate services have correlations with other services, which makes the corresponding tasks be correlated with each other. This...
