针对无人机集群对抗的规则与智能耦合约束训练方法

基于无人机集群智能攻防对抗构想,建立了无人机集群智能攻防对抗仿真环境。针对传统强化学习算法中难以通过奖励信号精准控制对抗过程中无人机的速度和攻击角度等问题,提出一种规则与智能耦合约束训练的多智能体深度确定性策略梯度(rule and intelligence coupling constrained multi-agent deep deterministic policy gradient, RIC-MADDPG)算法,该算法采用规则对强化学习中无人机的动作进行约束。实验结果显示,基于RIC-MADDPG方法训练的无人机集群对抗模型能使得红方无人机集群在对抗中的胜率从53%提高至79%,表明采用“智能体训练—发现问题—编写规则—再次智能体训练—再次发现问题—再次编写规则”的方式对优化智能体对抗策略是有效的。研究结果对建立无人机集群智能攻防策略训练体系、开展规则与智能相耦合的集群战法研究具有一定参考意义。

An Analysis of the Threat of Malicious Chemical Use by Nonstate Actors: Questioning the State-based Approach to Chemical Nonproliferation

ABSTRACT

This study seeks to evaluate the threat of malicious chemical use by non-state actors. It finds that non-state actors have primarily turned to ready-to-use crude chemical weapons (CW) instead of traditional CW agents. Interestingly, the worst crude CW attacks have been more destructive than those employing traditional CW. Scenarios for catastrophic consequences exist, but chemical attacks have typically been used to accomplish tactical goals, which leverage psychological and economic impacts. Therefore, successful efforts to counter CW proliferation by non-state actors must be substantially different from those targeting states.     

Reading the Riot Act: Toward a More Comprehensive Ban on Chemical Weapons

ABSTRACT

The recent use of chemicals in warfare in Syria and Iraq illustrates that, despite the important work of the 1997 Chemical Weapons Convention (CWC), the world has not yet been totally successful in stopping the use of indiscriminate toxic agents in conflicts, either by states or non-state actors. Michael Crowley's excellent and timely new book, Chemical Control, analyzes the use of “riot control agents” (RCAs) and “incapacitating chemical agents” (ICAs), including launch and dispersal systems, by police, paramilitary, and military forces over the last decades and raises the challenging question about where the red line might be drawn between banned and permitted uses of chemicals. He discusses this problem not only in the context of the CWC, which allows use of RCAs for civilian riot control, but also in the context of international law, human rights, and criminal justice, including the Biological and Toxin Weapons Convention and other disarmament and abolition regimes. He proposes a “holistic, three-stage approach” to addressing this issue “for effective regulation or prohibition of the weapon or weapon-related technology of concern.” As we approach the global abolition of a whole class of weapons of mass destruction in the next decade or even sooner, Chemical Control is helpful in better understanding and solving the dilemma of what's actually banned or permitted under international law, and precluding states undermining the chemical weapons ban.     

Gas,power, and norms: competing logics for the declining use of chemical warfare

ABSTRACT

What restrains states from employing chemical weapons during modern war? Despite widespread and consistent efforts by the international community to outlaw chemical weapons in the twentieth century, major deviations from this goal occur. Two of the strongest explanations that exist for this trend are the logics of deterrence and norms that consider the use of chemical weapons to be a taboo. We test these theories using factor analysis and find that norms provide a better explanation of non-use in the twentieth century among states with a chemical-weapon capability. We then conclude with avenues for future research in this burgeoning field of study, which includes closer qualitative examination of norms, as well as the expansion of the dataset to include intrastate warfare and non-state warfare.
