With the wide application of GIS to all kinds of fields, and developing of the technique of data mining and spatial data collection, the technique of data mining in spatial database-spatial data mining is coming out. In order to satisfy the people's demand for the interesting and potentially useful knowledge from the spatial database, this thesis used a wide using spatial clustering algorithm: k-means...
As a kind of intelligence computation method, evolutionary computation is widely applied and ceaselessly developed. Generally, it is made up of genetic algorithm, evolutionary strategies and evolutionary programming. And genetic algorithm is one of the most common ones, it has the features of easy structure and strong adaptability, achieves great success in many real fields, but it has much shortcomings...
In this paper, by introducing the concept of risk critical value of random variable, the risk critical value model based on objective benefit for random assignment problem are proposed. On the basis of characteristic of model, give the concrete implementation strategy and approach based on genetic algorithm (denoted by GARAP, for short), by combining numerical calculation method of probability and...
