First, the tracking errors of the system are driven to zero not only within the GP constraints but within an AT, which greatly enhances the execution efficiency.

This study develops a directionally asymmetric maximum-return consensus model (MRCM) with nonnegative return constraints, which shifts from a moderator-cost perspective to an individual-return perspective. To this end, a feasibility diagnosis approach integrating the minimum-slack feasibility checking model (MSFCM) and the relaxed MRCM is proposed to determine whether the MRCM is feasible. When it is not feasible, it further reveals whether the infeasibility originates from individual- or collective-level return deficits. Based on the diagnosis results, a twofold adaptive consensus framework is further developed: 1)internal compensation-driven feedback is applied when individual return deficits coexist with a nonnegative total cooperative return, reallocating surplus via an asymmetric Nash bargaining game (ANBG) without modifying the relaxed consensus outcome and 2)external compensation-driven feedback is activated when the total cooperative return is negative, with the moderator providing the minimum compensation to ensure consensus with nonnegative returns. The novelty of this work lies in developing a unified return-driven consensus mechanism governed by feasibility diagnosis by refining the new return formulation and compensation scheme. A numerical study based on the Dongjiang River Basin demonstrates that the proposed framework adaptively selects compensation strategies and effectively enhances consensus feasibility and stability.</p>","PeriodicalId":13112,"journal":{"name":"IEEE Transactions on Cybernetics","volume":"PP ","pages":""},"PeriodicalIF":10.5,"publicationDate":"2026-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147837294","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, comparatively limited attention has been directed toward the resilience of multiagent systems (MASs) under such attacks, particularly in the case of replay attacks. Addressing the challenge of resilience analysis in strict-feedback nonlinear MASs under replay attacks, this article proposes a dynamic stability analysis method based on a classical distributed adaptive consensus control framework. To evaluate the resilience of the MASs in the context of aperiodic replay attacks, a dynamic compact set model is designed as a resilience metric. An iterative algorithm is then developed to compute the upper bound of tracking error jump at the beginning and end of the attack. In the scenario where the control signals under replay attacks cannot be explicitly modeled, this study derives an upper bound on the variation of the tracking error during the attack period using the Lyapunov stability analysis. It is proven that resilience can be maintained when the resting time between two consecutive replay attacks satisfies a given sufficient condition.

Ulteriorly, the Hamilton-Jacobi-Isaacs equation, the optimal controls, and the worst disturbances are deduced for asymmetric constrained MZSGs (ACMZSGs). Since the acquired Hamilton-Jacobi-Isaacs equation is intractable to solve, an advanced critic learning scheme is built to attain the approximations of the optimal controls and the worst disturbances.

Combined prediction models (CPMs) have gained significant attention for their ability to integrate the strengths of multiple predictors, thereby improving prediction accuracy. Nevertheless, most current CPMs overlook the relationship between each predictor's output and the predicted sequences, resulting in suboptimal performance. To address these challenges, we propose an adaptive-network-based fuzzy inference system CPM (ANFIS-CPM) enhanced by an improved fuzzy $C$ -means (FCM) clustering, termed ANFIS-CPM-FCM. Our approach defines a similarity metric to quantify feature relationships, enhances traditional FCM to automatically determine the optimal number of clusters based on a density clustering model, trains separate ANFIS models on each cluster, and aggregates predictions by considering the relationships between each predictor's output and the predicted sequences.

Then, a language-guided query alignment (LQA) module is introduced to improve the semantic-aware object representation capability through vision-language query alignment. Finally, to accelerate the gaze point regression learning process, we design a language-guided direction prediction (LDP) module to introduce multimodal human gaze direction priors, thereby facilitating the human-target relationship construction.
