For a complex network, detecting the key links is of great importance. In recent years, many community detecting algorithms have been proposed, which have both advantages and disadvantages. In this paper, we propose and compare some classical community detecting algorithms and choose the best one of them to detect the key links of the complex network.
This paper is concerned with one kind of corporate optimal portfolio problems in the inflation case. The investor can put her or his money either in the bank account or in a real project. We use a conjecture method, which can often be found when studying linear quadratic (LQ) optimal control problem, to give an explicit solution to our optimal problem in the special constant relative risk aversion...
In this paper, we consider stochastic recursive optimal control problem of the stochastic delayed system described by forward-backward stochastic differential equation with delay. By virtue of classical spike variational approach, duality method and the anticipated backward stochastic differential equation, we obtain the maximum principle of the optimal control for this problem.
It is important to protect children from harmful effects of objectionable materials, such as pornography, which are now prevalent on the Internet. In this paper, a new method from the feature porno-sounds recognition point of view is proposed to detect adult video sequences automatically which serves as a complementary approach to the recognition method from image's point of view. To the special of...
