AOAAO: The Hybrid Algorithm of Arithmetic Optimization Algorithm With Aquila Optimizer

Abstract

Many new algorithms have been proposed to solve the mathematical equations formulated to describe the real-world problems. But there still does not exist one algorithm that could solve the problems all. And most of the proposed algorithms have defects in some aspects, they need to be improved in application. In order to find a more efficient optimization algorithm and inspired by the better performance of the Arithmetic Optimization algorithm (AOA) and Aquila Optimizer (AO), we proposed a hybridization algorithm of them and abbreviated AOAAO in this paper. Considering the better performance of the Harris Hawk optimization (HHO) algorithm, an energy parameter E was also introduced to balance the exploration and exploitation procedures of individuals in AOAAO swarms, and furthermore, piecewise linear map was introduced to decrease the randomness of the energy parameter. Pseudo code of the proposed AOAAO algorithm was presented, Simulation experiments were carried out on the benchmark functions and three classical engineering problems were also involved in optimization. Nine popular well demonstrated algorithms were included for comparison. Results confirmed the AOAAO would be more efficient in optimization with faster convergence rate, and higher convergence accuracy.INDEX TERMS Aquila optimizer (AO), arithmetic optimization algorithm (AOA), piecewise linear map, hybrid algorithm.

Deep Reinforcement Learning for Integrated Non-Linear Control of Autonomous UAVs

“…Empirical results as evidenced in Figure 1 retrieved from the analysis of [60] demonstrates that Adam works well in practice and compares favorably to other stochastic optimization methods besides bearing minimum training cost, however some people have also used derivative of DDPG for positive optimization [55]. Modern optimization algorithms such as Aquila Optimization Algorithm [61] and Hybrid Algorithm of Arithmetic Optimization Algorithm With Aquila Optimizer (AOAAO) [62], have special applications for machine learning based problem solving However, Adam which possess inherent advantages over the two other extensions of stochastic gradient descent namely Adaptive Gradient Algorithm (AdaGrad) and Root Mean Square Propagation (RMSProp) have been used in current research [63,64]. AdaGrad maintains a per-parameter learning rate which improves performance on problems with sparse gradients.…”

Aquila Optimization with Machine Learning-Based Anomaly Detection Technique in Cyber-Physical Systems

“…At this stage, the chosen features are passed into the ANFIS model and are utilized for the recognition of anomalies in the CPS environment. Generally, ANFIS produces a mapping among outputs and inputs by applying "IF-THEN rules" (otherwise called as "Takagi-Sugeno inference model") [19]. As shown, the input of Layer 1 is characterized as x and y, whereby the output of the ith node is signified as O 1i , as follows:…”
