Based on the characteristic of autonomous underwater vehicle path planning, the method of path planning was analyzed by genetic algorithm. Firstly, by means of grid, plan space was modeled into two markers. Best path was searched by genetic algorithm. Method of giving birth to initial groups was improved. Sufficiency function of path planning was given. Chamfer operator in genetic algorithm was imported...
Apache HBase is a column-oriented NoSQL key-value store built on top of the Hadoop distributed file-system. Logically, columns in HBase are grouped into column families. Physically, all columns in one column family are stored in the same set of files. Therefore the division of column families is closely related to the response time for a specific row query. In this paper, one new Evolutionary Algorithm...
Recommender system, which is powerful to deal with the issue of information overload, has been widely investigated by many researchers recently. However, one of the biggest challenges needs to face is the cold start problem. To address this problem, the data source from social network is incorporated into our recommender system in this paper. In a social network, users who tightly connected imply...
In this study, we propose a module-level Evolvable Hardware (EHW) approach to design synchronous sequential circuits and minimize the circuit complexity (the number of logic gates and wires used). Firstly, we use Genetic Algorithm (GA) to implement state simplification and obtain near-optimal state assignment. Then, in the pre-evolution stage, EHW evolves a set of high performing circuits and uses...
With the popularity of Web services, a set of Web services with similar functions but different qualities can be found. Since services are often be composed through a service process model, the way to compose them affects the whole quality of the process model itself. In this paper, a quality optimization method for the service process model is proposed, which takes the structure of service process...
For the capacitated minimum spanning tree problem (CMST), there are still no effective algorithms to solve this problem up to now. In this paper, we present a completely new approach by using the genetic algorithms (GAs). For the adaptation to the evolutionary process, we developed a tree-based genetic representation to code the candidate solution of the CMST problem. Numerical analysis shows the...
