The ubiquity of labor division within diverse social collectives is a topic well captured by evolutionary game theory. This work offers an integrative review of the evolutionary dynamics underpinning such division of labor from a tripartite standpoint—commencing with a theoretical exposition on numerous archetypes of labor division games. Subsequently, we delineate a suite of control strategies formulated to not only realize but also sustain the phenomenon of division of labor. This is followed by an elucidation of practical implementations pertaining to the allocation of tasks and labor division, grounded in the principles of game theory. We culminate with the proposition of prospective avenues and insightful trajectories for future investigations, cultivating a frontier for the continued exploration within this field.

The assignment of tasks for unmanned aerial vehicles (UAVs) during forest fire reconnaissance is a highly complex and large-scale problem. Current task allocation methods struggle to strike a balance between solution speed and effectiveness. In this paper, a two-phase centralized UAV task assignment model based on expectation maximization (EM) clustering and the multidimensional knapsack model (MKP) is proposed for the forest fire reconnaissance task assignment. The fire situation information is acquired using the sensors carried by satellites at first. Then, the EM algorithm based on the Gaussian mixture model (GMM) is applied to get the initial position of every UAV. In the end, the MKP is applied for UAV task assignment based on the initial positions of the UAVs. An improved genetic algorithm (GA) based on the fireworks algorithm (FWA) is proposed for faster iteration speed. A simulation was carried out against the background of forest fires in Liangshan Prefecture, Sichuan Province, and the simulation’s results demonstrate that the task assignment model can quickly and effectively address task allocation problems on a large scale. In addition, the FW–GA hybrid algorithm has great advantages over the traditional GA, particularly in solving time, iteration convergence speed, and solution effectiveness. It can reduce up to 556% of the iteration time and increase objective function value by 1.7% compared to the standard GA. Furthermore, compared to the GA–SA algorithm, its solving time is up to 60 times lower. This paper provides a new idea for future large-scale UAV task assignment problems.

“…When the nodes are equally weighted, we have the minimum vertex cover (MVC) problem, the decision version of which is among Karp's 21 NP complete problems [2], [3]. Besides, as it well represents cooperative decision-making issues in many multiagent scenarios, a series of real-world applications has also been found, ranging from wireless sensor networks, wireless communication, computer network security, and mission scheduling [4]- [9]. For instance, by deploying sensors at vertices of the MWVC, we could surveil all the roads in a transport network with the minimum cost [10].…”

Toward better approximation for the minimumweighted 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.
