竞争环境中学习算法的预检测机制

多Agent系统中(MAS),所有的Agent都在不断学习,对于单个Agent来说就是一个学习移动目标的问题.PHC(policy hill climb)算法理性但自博弈时并不收敛.不过,PHC自博弈时的平均策略却能够快速且精确地收敛到纳什均衡(NE).在一些需要NE作为先验知识或需要收敛到NE的算法中,可以通过增加一个PHC自博弈过程来估计NE,然后再根据对手策略采取进一步措施.这样,不仅可以避免使用其他算法计算NE,而且能够使学习者至少获得均衡回报.Exploiter-PHC算法(Exploiter算法)能够击败大多数公平对手但需要NE作为先验知识,且自博弈时也不收敛.在其中加入预检测过程后的算法ExploiterWT(exploiter with testing)能够收敛且不需要先验知识.除此之外,该过程也可以加入其他一些算法之中.

Fixed-Time Consensus-Based Nash Equilibrium Seeking

<正>Dear Editor, This letter examines the fixed-time stability of the Nash equilibrium(NE) in non-cooperative games. We propose a consensus-based NE seeking algorithm for situations where players do not have perfect information and communicate via a topology graph. The proposed algorithm can achieve NE in a fixed time that does not depend on initial conditions and can be adjusted in advance. In this strategy,

Nash equilibrium seeking with prescribed performance

In thiswork,we study aNash equilibrium (NE) seeking problem for stronglymonotone non-cooperative games with prescribed performance. Unlike general NE seeking algorithms, the proposed prescribed-performance NE seeking laws ensure that the convergence error evolves within a predefined region. Thus, the settling time, convergence rate, and maximum overshoot of the algorithm can be guaranteed. First, we develop a second-order Newton-like algorithm that can guarantee prescribed performance and asymptotically converge to the NE of the game. Then, we develop a first-order gradient-based algorithm. To remove some restrictions on this first-order algorithm, we propose two discontinuous dynamical system-based algorithms using tools from non-smooth analysis and adaptive control. We study the special case in optimization problems. Then, we investigate the robustness of the algorithms. It can be proven that the proposed algorithms can guarantee asymptotic convergence to the Nash equilibrium with prescribed performance in the presence of bounded disturbances. Furthermore, we consider a second-order dynamical system solution. The simulation results verify the effectiveness and efficiency of the algorithms, in terms of their convergence rate and disturbance rejection ability.

New directions in distributed Nash equilibrium seeking based on monotone operator theory

There has been an increasing research interest in modeling, optimization and control of various multi-agent networks that have wide applications in industry, defense, security, and social areas, such as computing clusters, interconnected micro-grid systems, unmanned vessel swarms \cite{ChenJie}, power systems\cite{MeiS}, multiple UAV systems\cite{KolaricP} and sensor networks\cite{LiuR}. For non-cooperative agents that only concern selfish profit-maximizing, the decision making problem can be modelled and solved with the help of game theory, while Nash equilibrium (NE) seeking is at the core to solve the non-cooperative multi-agent games \cite{HenrikSandberg, IsraelAlvarez, Jong-ShiPang}. Distributed NE seeking methods are appealing compared with the center-based methods in large-scale networks due to its scalability, privacy protection, and adaptability. Recently, monotone operator theory is explored for distributed NE seeking, which is shown to provide an uniform framework for various algorithms in different scenarios. It has been gradually developing into a cutting-edge research field, with the prospect and necessity of future in-depth research. In non-cooperative multi-agent games, each agent has different characteristics and pursues maximizing its own benefit. Hence, there is no centralized manager that can force all agents to adopt specified strategies to optimize the overall benefits. Under the NE, no player can decrease its cost by unilaterally changing its local decision to another feasible one. To seek an NE, the agent is required to optimize its own objective function given the opponent''s countermeasures. Therefore, various optimization-based methods have been investigated for distributed NE seeking, such as the gradient flow method and the best response method....

基于QSA数组计算序列中所有NE重复模式的算法

序列中重复模式的识别与提取算法在数据挖掘、模式识别、数据压缩、生物信息学等领域中具有广泛的实际应用。提出一种全新的基于QSA数组计算所有带有约束条件的NE重复模式的算法RPT。算法设计中充分考虑了NE重复模式的特征,以建立特征和重复模式检测结果之间的统计联系;算法中的约束条件包括最小周期pmin和最大间距gmax,其可用于筛选符合条件的NE重复模式,并可按照递增序输出所有NE重复模式的出现位置。与已有的基于后缀索引的算法相比,此算法的空间效率得到了提高。在分类属性数据样本集上进行的实验表明,算法RPT对生物序列尤其是DNA序列以及维吾尔语Web文本中NE重复模式的识别与提取都很有效。
