Simulated annealing (SA) algorithm is a popular intelligent optimisation algorithm, but its efficiency is unsatisfactory. To improve its efficiency, this paper presents a swarm SA (SSA) algorithm by exploiting the learned knowledge from searching history. In SSA, a swarm of individuals run SA algorithm collaboratively. Inspired by ant colony optimisation (ACO) algorithm, SSA stores knowledge in...

This paper proposes a model for mining frequent patterns in large databases by implementing a matrix approach. The whole database is scanned only once and the data is compressed in the form of a matrix. The frequent patterns are then mined from this compressed database which brings efficiency in data mining, as the number of database scans is effectively less than two. The computation time is r...

The negotiation process of the Service Level Agreement (SLA) in cloud environment is an interaction process of access control rules and credentials. Due to the mass of credentials in cloud environment, the negotiation efficiency is not high. To address the problem, this paper proposes an Automated Trust Negotiation (ATN) model based on Colored Petri Net (CPN), which exists a legitimate occurren...

Parallel planning is a paradigm that provides interesting efficiency improvements in the field of classical AI planning and it is one of the key components of successful SAT-based planers. Popularized by the Graphplan algorithm, it provides more structure information about the plan for a plan executor when compared to the traditional sequential plan, which is one of the crucial facts of its usa...

In this paper, an optimum-efficiency control scheme of synchronous reluctance motors is presented. There exists a variety of combinations of dand q-axis current which provides a specific motor torque. The objective of the optimum-efficiency controller is to seek a combination of dand q-axis current components, which provides minimum input power, that is, minimum losses at a certain operating po...

Recently Peer-to-Peer networks (P2P) have gained great attention and popularity. One key challenging aspect in P2P resource sharing environments is efficient searching algorithm. This is especially important for Gnutella-like decentralized and unstructured networks since they have power-law degree distributions. A robust search algorithm should respond to the query message promptly without gene...
