An effective hybrid cuckoo search algorithm (CS) with improved shuffled frog-leaping algorithm (ISFLA) is put forward for solving 0-1 knapsack problem. First of all, with the framework of SFLA, an improved frog-leap operator is designed with the effect of the global optimal information on the frog leaping and information exchange between frog individuals combined with genetic mutation with a sm...

Recent day power system networks are having high risks of voltage instability problems and several network blackouts have been reported. This phenomenon tends to occur from lack of reactive power supports under heavily stressed operating conditions caused by increased load demand and the fast developing deregulation of power systems across the world. This paper proposes an application of Shuffl...

IT IS NOW more than two years since ~he representatives of Canadian universities reported before the Society their initial ~tudies with halothane, and in the interim the pharmacology and clinical use of halofllane have been extensiv01y investigated. Though the cardiovascular effects a halotliane and of chloroform are strikingly sfla~flar, there is as yet no,'concrete 6vidence that halothane is ...

in distribution systems, in order to diminish power losses and keep voltage profiles within acceptable limits, network reconfiguration and capacitor placement are commonly used. in this paper, the hybrid shuffled frog leaping algorithm (hsfla) is used to optimize balanced and unbalanced radial distribution systems by means of a network reconfiguration and capacitor placement. high accuracy and ...

This study investigates a hybrid algorithm between Grey Wolf Optimization (GWO) and Cuckoo Search (CS) algorithms to find the parameters of induction motors. The motor have been estimated by using data supplied manufacturer. problem for parameter estimation is formulated as an optimization problem. Then, solved GWO based on CS parameters. Numerical results show that both are capable solving fin...

in emerging electric power systems, increased transactions often lead to the situations where the system no longer remains in secure operating region. the flexible ac transmission system (facts) controllers can play an important role in the power system security enhancement. however, due to high capital investment, it is necessary to locate these controllers optimally in the power system. facts...

Service-oriented architecture provides the ability to combine several web services in order fulfil a user-specific requirement. In dynamic environments, appearance of unforeseen events can destabilize composite service (CWS) and affect its quality. To deal with these issues, must be dynamically reconfigured. Dynamic reconfiguration may enhanced by avoiding invocation degraded predicting QoS for...
