This article deals with the solution of convex quadratic programs by iteratively solving a master problem and a subproblem as proposed previously by Sacher. The approach has the advantage that the subproblems are linear programs so that advantage can be taken of existing schemes for solving large linear problems. At each step in solving the master problem, a closed-form solution can be specified so that the procedure is well suited for solving large quadratic programs and can take advantage of the constraint structure. 相似文献

Strategists and military professionals have previously questioned many of the methodological (theoretical underpinnings, the principles, and rules applied by the discipline) decisions associated with American military strategy, but the direction this essay takes is above and beyond the common methodological rivalries in how we pursue strategic desired future states. To get beyond methodological disputes entirely, we must consider thinking about our thinking as an organization on American strategy. Thus, this article hovers between philosophies, organizational theory, as well as our usually unquestioned belief in something called “strategy”. Questioning things about our basic understanding of the world tends to trigger strong organizational defense mechanisms, for good reason. Critical reflection at deep levels puts our worldview, and our role within it at stake. Nonetheless, as strategic disappointment emerges over multiple complex conflict developments, even the most cherished and guarded choices on how the world ought to work are ripe for critical inquiry. This essay examines the limited single strategic paradigm of the US defense industry and how the latest American National Security Strategy and Army Future Operating Concept (Win in a Complex World through 2030) presents a flawed strategic position. This essay presents valid alternative strategies that operate within different paradigmatic constructs. 相似文献

作为一种基于模型的脆弱性分析技术,攻击图能够识别网络中存在的脆弱性和它们之间的相互关系,分析出可能的攻击路径和潜在威胁.论文在攻击图的基础上提出了警报关联图的概念,利用攻击图中蕴含的脆弱性先验知识,将实时IDS警报信息映射到攻击路径,动态反映攻击进程和攻击者意图.在此基础上提出了一种基于警报关联图的网络脆弱性量化评估方法,通过计算警报关联边的权值对网络脆弱性进行动态分析,这种方法结合了静态的网络脆弱性先验知识和动态变化的攻击者意图,能有效反映网络脆弱性在动态攻击情况下的变化. 相似文献

Understanding contemporary conflicts in Africa remains directly dependent on the approaches employed to decipher or interpret them. This article first examines the bias of conventional approaches (inherited from the Cold War) and then those of a series of supposedly “newer” approaches. Relying primarily on West African examples, it offers a brief overview of current knowledge, issues, and avenues for research, based on three apparent characteristics of a “new generation” of conflicts: the regionalization of wars, the privatization of violence and security, and the recourse to extreme forms of brutality. These three major trends bear witness to a rapid transformation of war and armed violence over the past 20 years, but they are not sufficient to establish a radical historical break between “old” and “new” conflicts in Africa. By concealing elements of continuity a priori, the most influential “new” approaches actually make it impossible to ponder their own limits. To that end, fashionability and struggles for influence within the Africanist field play a major role in perpetuating dominant, sensationalistic, or simplistic (and invariably incorrect) portrayals of African conflicts. 相似文献
