人工股市(Artificial Stock Market,简称ASM)是模拟股市运作的一个程序。在这个电脑中的虚拟市场中,若干被称为交易者的人工智能程序(Agent)通过观察它们所在的数字世界中股价和股息的不断变换而做出预测,并且根据这些预测做出购买股票与否以及购买股票数量的决策。反过来,所有的交易者的决策又决定了股票的价格,这样,整个的股票交易市场就构成了一个自我封闭的计算系统。同时,这些交易者都具有学习的能力,可以根据以前预测的成功或者失败对自己的决策进行调整,并且通过一种被称为遗传算法的方法产生创新能力。总之,ASM是一个电脑中不断进化的虚拟股票市场!通过研究ASM,我们可以更好的理解现实世界的行为,并且它提供了一个很好的现实股市的隐喻。 备注:该程序运行需要有Swarm平台的支持,关于这个平台可以到http://www.swarm.org免费下载。

The ICA/BSS algorithms are pure mathematical formulas, powerful, but rather mechanical procedures: There is not very much left for the user to do after the machinery has been optimally implemented. The successful and efficient use of the ICALAB strongly depends on a priori knowledge, common sense and appropriate use of the preprocessing and postprocessing tools. In other words, it is preprocessing of data and postprocessing of models where expertise is truly ne

This the specification of the Enterprise JavaBeansTM architecture.The Enterprise JavaBeans architecture is a component architecture for the development and deployment of componentbased distributed business applications. Applications written using the Enterprise JavaBeans architecture are scalable, transactional, and multi-user secure. These applications may be written once, and then deployed on any server platform that supports the Enterprise JavaBeans specification.

Setting and Changing Column Widths By default, all columns in a table start out with equal width, and the columns automatically fill the entire width of the table. When the table becomes wider or narrower (which might happen when the user resizes the window containing the table), all the column widths change appropriately.

The code is fairly straightforward, except perhaps for the call to convertColumnIndexToModel. That call is necessary because if the user moves the columns around, the view s index for the column doesn t match the model s index for the column. For example, the user might drag the Vegetarian column (which the model considers to be at index 4) so it s displayed as the first column — at view index 0. Since prepareRenderer gives us the view index, we need to translate the view index to a model index so we can be sure we re dealing with the intended column
