针对传统混合模糊测试提升技术多聚焦于利用多种动静态分析手段辅助而忽略了混合符号执行自身性能的问题,提出一种混合模糊测试平衡点模型,并基于该模型对主流混合符号执行方案进行剖析,包括污点分析辅助模糊测试、混合模糊测试以及混合符号执行,归纳了6种符号执行方案,基于混合符号执行引擎Triton复现了6种符号执行方案,并通过10个典型真实程序进行了测试评估。从效率、内存、覆盖率三个维度对各个方案进行性能对比与影响因素分析。实验证明,优化方案都可以消除不必要的约束并减少时间和空间开销,但约束缩减会造成信息丢失,造成覆盖率降低。基于实验数据分析,提出了一个优化方案的性能序列,并提出三种针对不同测试需求的优化方案。 相似文献

This article looks at the Kashmir conflict in South Asia, which has been going on since 1947, when India and Pakistan became independent from British colonial rule. After looking at some historical background, the article looks at both the external dimension as well as the internal dimension of the conflict. The external dimension tends to focus on Indo-Pak relations over Kashmir and the internal dimension looks at India's repressive state policies within the state of Kashmir. This article uses Mary Kaldor's “New War” thesis as a theoretical framework to understand the situation and pays special attention to the conflict's very complex and multifaceted nature. The article argues that although the levels of violence have differed from time to time in the region since 1947, today the conflict seems to have less to do with Indo-Pak relations or the external side of things and has more to do with the internal dimension and India's undemocratic ways within Kashmir. Today, Kashmir is one of the most militarised conflict zones in the world. The stationing of the Indian military and paramilitary forces in the region has only exacerbated the situation since it is the security personnel who cause much of the problem. The Armed Forces Special Powers Act gives these security forces extraordinary powers in the region, which they often abuse. The armed forces have no real understanding of the local culture or sympathy for local religious sentiments. Poverty, corruption, administrative failure, police brutality, identity politics and human rights abuses are some of the key features associated with this conflict. Methodologically, a number of interviews were carried out with the local people in the region recently. From the data gathered through the interviews, it is very obvious that the people still feel very oppressed and that the situation is still very volatile, fraught with uncertainty. Finally, after making an assessment of the situation, the article tries to suggest methods of peaceful building and conflict management as the way forward. 相似文献

Graph association is the problem of merging many graphs that collectively describe a set of possibly repetitive entities and relationships into a single graph that contains unique entities and relationships. As a form of data association, graph association can be used to identify when two sensors are observing the same object so information from both sensors can be combined and analyzed in a meaningful and consistent way. Graph association between two graphs is related to the problem of graph matching, and between multiple graphs it is related to the common labeling of a graph set (also known as multiple graph matching) problem. This article contribution is to formulate graph association as a binary linear program and introduce a heuristic for solving multiple graph association using a Lagrangian relaxation approach to address issues with between‐graph transitivity requirements. The algorithms are tested on a representative dataset. The developed model formulation was found to accurately solve the graph association problem. Furthermore, the Lagrangian heuristic was found to solve the developed model within 3% of optimal on many problem instances, and found better solutions to large problems than is possible by directly using CPLEX. © 2013 Wiley Periodicals, Inc.

While Carl von Clausewitz has generally been respected as one of the most profound philosophers of war, his expertise has been regarded as somewhat limited if not even irrelevant to the so-called ‘new wars’ of the post-Cold War world. Many scholars in international relations have claimed that ‘new wars’ are essentially ‘post-Clausewitzian’ and ‘post-trinitarian’ in nature, meaning that they are no longer fathomable through a Clausewitzian framework. However Clausewitz's earlier writings were nearly exclusively dedicated to guerrilla warfare, or what he called ‘small wars’. These writings have been largely overlooked by many analysts of contemporary conflicts. By drawing on his rare and untranslated writings, the article uncovers a critical part of Clausewitz's expertise in asymmetric warfare and shows that, far from being irrelevant in an age where interstate warfare is increasingly being replaced by conflicts between states and semi-/non-state actors, Clausewitz's philosophical writings actually shed new light into the particular interactive dynamics generated during wars waged under conditions of asymmetry. 相似文献

所谓新型毒品是相对鸦片、海洛因等传统毒品而言的,主要指人工化学合成的致幻剂、兴奋剂类毒品,是由国际禁毒公约和我国法律法规所规定管制的、直接作用于人的中枢神经系统,使人兴奋或抑制,连续使用能使人产生依赖性的精神药品。中国每年被冰毒、氯胺酮等新型毒品吞食的社会财富以百亿计。新型毒品犯罪给我国禁毒工作带来了新挑战,在分析新型毒品犯罪特点的基础上,找出打击新型毒品犯罪所面临的问题,构建科学的新型毒品犯罪打防控对策。 相似文献
