一类0.1矩阵变换图的边连通性 总被引:1,自引:0,他引:1
Let U (R, S) denote the class of all m×n matrices of 0's and 1's havingrow sum vector R and column sum vector S. The interchange graph G (R,S)is the graph where the vertices are the matrices in U (R, S) and where twomatrices are joined by an edge provided they differ by an interchange. Brualdishowed that the connectivity of G(R, S) is at least two. In the present paperwe prove that the edge connectivity of G(R, S) is equal to the minimum degreeof vertices of G(R, S) 相似文献

Method of sequential mesh on Koopman-Darmois distributions 总被引:1,自引:0,他引:1

For costly and/or destructive tests,the sequential method with a proper maximum sample size is needed.Based on Koopman-Darmois distributions,this paper proposes the method of sequential mesh,which has an acceptable maximum sample size.In comparison with the popular truncated sequential probability ratio test,our method has the advantage of a smaller maximum sample size and is especially applicable for costly and/or destructive tests. 相似文献

成功的海盗或政府核准的私掠船一定是“理船有方”的,他们不仅组织有序,而且是最早得到风投资本家支持的“企业”。CFO们也许可以学习—下这些“好汉”的经济学。 相似文献

动态自融资与消费策略的多目标控制模型 总被引:1,自引:0,他引:1
在不考虑交易费用的前提下,本文研究了投资者最优动态自融资与消费策略,建立了两种多目标控制模型,分别考虑了使投资者的累积消费效用与/或拥有的财富的效用较大风险较小两个目标。对传统的侧重于单纯追求消费或财富效用达到极大的方法进行了改进,给出了相关分析结果。 相似文献

In this paper, we show the invariance principle for the partial sum processes of fractionally integrated processes, otherwise known as I(d + m) processes, where |d| < 1/2 and m is a nonnegative integer, with strong near-epoch dependent innovations. The results are applied to the test of unit root. The conditions given improve previous results in the literature concerning fractionally integrated processes. 相似文献
