This paper proposes an approximate optimization algorithm combining P systems with ant colony optimization, called ACOPS, to solve traveling salesman problems, which are well-known and extensively studied NP-complete combinatorial optimization problems. ACOPS uses the pheromone model and pheromone update rules defined by ant colony optimization algorithms, and the hierarchical membrane structur...

In this work we introduce and evaluate a model of Hierarchical Reinforcement Learning with Parameters. In the first stage we train agents to execute relatively simple actions like reaching or gripping. In the second stage we train a hierarchical manager to compose these actions to solve more complicated tasks. The manager may pass parameters to agents thus controlling details of undertaken acti...

Abstract Manta ray foraging optimization (MRFO) tends to get trapped in local optima as it relies on the direction provided by previous individual and best guidance search for optimal solution. As enriching population diversity can effectively solve this problem, paper, we introduce a hierarchical structure weighted fitness-distance balance selection improve of algorithm. The allows individuals...
