Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of multi-agent game decision making, and in particular relates to a method for searching for a designated time for a balanced resource allocation game of unrelated multi-cluster resources within a group. Background Art
[0002] With the development of artificial intelligence, resource allocation has become an important factor in promoting the development of modern industrial systems. It can optimize resource utilization under limited resources and play an important role in economic development, cultural construction, green development, etc. In the resource allocation of large-scale networked systems, the system is clustered into multiple clusters that only focus on maximizing the interests of the group they belong to. Multi-cluster resource allocation can be regarded as a distributed optimization problem for multiple clusters under the resource equation coupling constraint to maximize the group benefits. The group benefits are usually only related to the decisions of individuals in the cluster. However, in the actual application of multi-cluster resource allocation, due to the complex interactions in large-scale networked systems, there are competitive and cooperative relationships between different cluster agents, and the local decisions of individuals will also affect the cost functions of other cluster agents. Therefore, it is urgent to establish a multi-cluster resource allocation game that can describe the conflicts of interest between different cluster agents, design and optimize the parameters of the multi-cluster resource allocation game model, and conduct research on its Nash equilibrium search method.
[0003] Among the existing multi-cluster game Nash equilibrium search algorithms, the literature ( Pang Y, Hu G. Nash equilibrium seeking in N - coalition games via a gradient - free method[J]. Automatica, 2022, 136: 110013. ) In the case where only local objective functions can be obtained, a discrete-time algorithm without gradient is proposed based on Gaussian smoothing. Under this algorithm, all agents converge to the minimum neighborhood of Nash equilibrium at a geometric rate. The limitation of this scheme is that it is not applicable to the situation with constraints and can only converge linearly to the neighborhood of Nash equilibrium. Meng M, Li X. On the linear convergence of distributed Nash equilibrium seeking for multi - cluster games under partial - decision information[J]. Automatica, 2023, 151: 110919 .) studied the Nash equilibrium search algorithm for multi-cluster games under consistency constraints, and designed a discrete time algorithm based on gradient tracking and projection method in partial decision information scenarios. However, this algorithm is only applicable to undirected topological graphs and can only achieve linear convergence, not specified time convergence. Zhou J, Lv Y, Wen G, et al. Distributed Nash equilibrium seeking in consistency - constrained multicoalition games[J]. IEEE Transactions on Cybernetics, 2022. ) further studied the multi-cluster game under the directed topology graph that satisfies the consistency constraint, and designed a discrete time algorithm using techniques such as leader-follower consistency and pseudo gradient descent, but this scheme can only achieve linear convergence. The above schemes can only achieve linear convergence and cannot achieve specified time convergence. Therefore, the existing technology is not suitable for practical applications with specified convergence time requirements. Summary of the invention
