2025 CCA: A Novel Camouflage Coating Attack on Object Detectors in Remote Sensing Images
abstract
Adversarial patch-based physical attacks have attracted growing attention, yet their effectiveness in deceiving aerial detection systems remains underexplored. Existing methods typically rely on carefully designed adversarial patches with specific shapes, strategically placed in or around the target. However, for small-scale remote sensing objects, these approaches often suffer from limited attack efficacy and poor transferability. Furthermore, the conspicuous nature of these patches makes them easily identifiable by human observers, undermining the fundamental principle of adversarial examples. To address these challenges, this article proposes a novel camouflage coating attack (CCA), a physical attack method specifically designed for remote sensing targets, exhibiting high attack effectiveness and strong transferability. During training, the adversarial coating is precisely applied to the target using a dedicated coating application algorithm, followed by pixel-level iterative optimization to enhance its real-world attack efficacy. To improve stealthiness, we introduce a sophisticated loss function that generates covert adversarial patterns while preserving camouflage characteristics. We rigorously evaluate CCA through black-box and white-box attack experiments on multiple object detectors, along with transferability assessments and perceptibility analyses of the generated camouflage patterns. Experimental results demonstrate that CCA achieves an attack success rate (ASR) of up to 82.96%, reducing the average precision (AP) to as low as 14.12%. This study establishes a new benchmark for assessing the adversarial robustness of object detectors and their defense mechanisms. By introducing this novel attack paradigm, we aim to inspire future advancements and challenges in adversarial research in the domains of remote sensing and object detection.

2024 Mechanism Design for Distributed Weighted Set Cover via Learning in Ordinal Potential Games
abstract
Aiming for efficient coordination mechanisms for the distributed weighted set cover problem, we study from ordinal potential game theoretic learning and propose a Nash equilibrium selection algorithm (NESA). An ordinal potential game model is established, where the local utility function is designed by incorporating a greedy heuristic. To distinguish Nash equilibria of different global fitness, we further classify them into the inferior Nash equilibrium (INE) and the superior Nash equilibrium (SNE), and show that the optimal solution must be an SNE. High-quality SNE solutions are obtained by assigning each player a local stochastic rule based on its category and a finite memory. By demonstrating the existence of a finite improvement path from each INE to an SNE, we prove finite-time convergence of the NESA. Numerical experiments are carried out and comparisons against representative methods are presented, which demonstrate the effectiveness as well as the superiority of our methodology to the state-of-the-art.

2022 Better Approximation for Distributed Weighted Vertex Cover via Game-Theoretic Learning
abstract
Toward better approximation for the minimum-weighted vertex cover (MWVC) problem in multiagent systems, we present a distributed algorithm from the perspective of learning in games. For self-organized coordination and optimization, we see each vertex as a potential game player who makes decisions using local information of its own and the immediate neighbors. The resulting Nash equilibrium is classified into two categories, i.e., the inferior Nash equilibrium (INE) and the dominant Nash equilibrium (DNE). We show that the optimal solution must be a DNE. To achieve better approximation ratios, local rules of perturbation and weighted memory are designed, with the former destroying the stability of an INE and the latter facilitating the refinement of a DNE. By showing the existence of an improvement path from any INE to a DNE, we prove that when the memory length is larger than 1, our algorithm converges in finite time to DNEs, which could not be improved by exchanging the action of a selected node with all its unselected neighbors. Moreover, additional freedom for solution efficiency refinement is provided by increasing the memory length. Finally, intensive comparison experiments demonstrate the superiority of the presented methodology to the state of the art, both in solution efficiency and computation speed.

2022 Toward Refined Nash Equilibria for the SET K-COVER Problem via a Memorial Mixed-Response Algorithm
abstract
Area coverage and network lifetime are two contradictory issues to the architecture development of a wireless sensor network (WSN). A satisfactory balance could be achieved by deploying abundant sensor nodes randomly and dividing them into$k$exclusive cover sets. Toward self-organized partition with higher efficiency, we address the problem from the perspective of networked potential games and propose a memorial mixed-response algorithm (MMRA), which is implemented in a distributed and synchronous manner. Being viewed as a game player, each sensor node first updates its memory using a temporary action, which is generated by following a mixed response rule. After this, the coordination evolves into the next iteration by each player randomly drawing an action from its memory with equal probabilities. We prove that our algorithm converges with probability 1 to a convention of Nash equilibria, with the worst approximation ratio strictly larger than 0.5. Moreover, it is also found that a tradeoff between solution efficiency and computation time could be achieved via the adjustment of the amount of randomness introduced via the memory length$m$as well as the probability$p_{m}$, where better partition results are more likely to be generated using a larger$m$and smaller$p_{m}$. Comparisons with existing distributed methods demonstrate the superiority of our method in terms of solution refinement as well as convergence speed.

2019 A Game Theoretic Solver for the Minimum Weighted Vertex Cover
abstract
Toward the global optimality and computation time reduction, we address the minimum weighted vertex cover (MWVC) problem by proposing a population based game theoretic optimizer (PGTO) that combines learning in games with population based optimization. A population of candidate solutions are iterated through the procedures of swarm evolution (SE), learning in games (LIG), and local search (LS). Via strict theoretic analysis, we prove that LIG converges with probability one to Nash equilibria which could be further refined by LS. Numerical simulations show that a larger population size and a proper mutation probability are more likely to provide the best performance. Comparison experiments with typical algorithms demonstrate the superiority of the presented methodology to the state of the art, both in terms of solution efficiency and computation time.

2019 Potential Game Theoretic Learning for the Minimal Weighted Vertex Cover in Distributed Networking Systems
abstract
Toward the minimal weighted vertex cover (MWVC) in agent-based networking systems, this paper recasts it as a potential game and proposes a distributed learning algorithm based on relaxed greed and finite memory. With the concept of convention, we prove that our algorithm converges with probability 1 to Nash equilibria, which serve as the bridge connecting the game and the MWVC. More importantly, an additional degree of freedom is also provided for equilibrium refinement, such that increasing memory lengths and mutation probabilities contributes to the improvement of system-level objectives. Comparisons with typical methods, centralized and distributed, demonstrate the advantage of our algorithm for both weighted and unweighted versions. This paper not only provides a useful tool for the MWVC problem in decentralized environments but also paves an effective way for distributed coordination and optimization that could be modeled as potential games.

2018 Distributed Satellite Mission Planning via Learning in Games
abstract
Mission planning for a cluster of earth observing satellites is a complex problem that raises significant theoretical and technological challenges, especially in distributed environments. Towards efficient cooperation relying on local information only, we cast the problem into a networked potential game by viewing each satellite as a rational player and propose a distributed coordination and optimization algorithm. By each player interacting with the neighbors and adapting the local plan following a restricted greed and memory based rule, stable Nash equilibria are proven to emerge with probability 1. Moreover, with the increase of randomness introduced by a longer memory, a refined Nash equilibrium can also be guaranteed, which corresponds to closer cooperation among individual satellites and better system-level performance. Comparison experiments with typical methods, centralized and distributed, highlight the advantages of the presented methodology.

2018 Distributed Lost-in-Space Localization in Sensor Networks Using Range Measurements
abstract
Sensor location is important to sensor networks since many cooperative tasks depend on it. Focusing on the lost-in-space localization problem without prior location knowledge, this paper describes a self-organized and fully distributed algorithm where nodes start from a random guessed coordinate assignment and converge to a consistent solution with actual locations using ranging measurements and neighboring interaction only. It is most likely for this algorithm to overcome local minima and result in the global optimum by introducing an improved interacting mechanism where nodes interact according to a simulated switching computational topology. Numerical simulations demonstrate the effectiveness and robustness of the algorithm.

2018 A Time Variant Log-Linear Learning Approach to the SET K-COVER Problem in Wireless Sensor Networks
abstract
Toward the global optimality of the SET K-COVER problem in wireless sensor networks, we view each sensor node as a rational player and propose a time variant log-linear learning algorithm (TVLLA) that relies on local information only. By defining the local utility as the normalized area covered by one node alone, we formulate the problem as a spatial potential game. The resulting optimal Nash equilibria correspond to the optimal partition. Such equilibria are obtained by designing a time varying parameter that approaches infinity with time. Using inhomogeneous Markov chain theory, we prove that the TVLLA guarantees convergence to the optimal solution with probability 1. Comparison results against traditional methods demonstrate that the algorithm can also provide better near-optimal solutions in a reasonable computation time than the state-of-the-art. Our findings pave a new way to reach the global optimality of the SET K-COVER problem in a distributed manner as well as other potential games from the view of self-organized optimization.

2017 A fast recognition algorithm for star identification of star trackers
abstract
This paper focuses on recognizing the correct match of star identification among multiple possible candidates for star trackers. Derived from the perturbation theory, a tolerance criterion is proposed and proved to check the correctness of the candidates. A recognition algorithm is then proposed based on the tolerance criterion to select the correct match. Compared to traditional recognition algorithms, the proposed algorithm provides a straightforward and deterministic procedure and avoids non-deterministic, time-consuming, inefficient lookingup operations. Finally, simulation examples are given to show processing details and verify the proposed algorithm.
