Abstract Over recent decades, research in Artificial Intelligence (AI) has developed a broad range of approaches and methods that can be utilized or adapted to address complex optimization problems. As real-world problems get increasingly complicated, this requires an effective optimization method. Various meta-heuristic algorithms have been developed and applied in the optimization domain. This paper used and ameliorated a promising meta-heuristic approach named Crow Search Algorithm (CSA) to address numerical optimization problems. Although CSA can efficiently optimize many problems, it needs more searchability and early convergence. Its positioning updating process was improved by supporting two adaptive parameters: flight length (fl) and awareness probability (AP) to tackle these curbs. This is to manage the exploration and exploitation conducts of CSA in the search space. This process takes advantage of the randomization of crows in CSA and the adoption of well-known growth functions. These functions were recognized as exponential, power, and S-shaped functions to develop three different improved versions of CSA, referred to as Exponential CSA (ECSA), Power CSA (PCSA), and S-shaped CSA (SCSA). In each of these variants, two different functions were used to amend the values offlandAP. A new dominant parameter was added to the positioning updating process of these algorithms to enhance exploration and exploitation behaviors further. The reliability of the proposed algorithms was evaluated on 67 benchmark functions, and their performance was quantified using relevant assessment criteria. The functionality of these algorithms was illustrated by tackling four engineering design problems. A comparative study was made to explore the efficacy of the proposed algorithms over the standard one and other methods. Overall results showed that ECSA, PCSA, and SCSA have convincing merits with superior performance compared to the others.

For the synchronization and control of fractional-order chaotic systems, knowing parameters and orders is essential as well as being a hot topic. In this paper, the problem of parameters and orders identification is transformed into a multidimensional optimization problem. Five of the latest metaheuristic methods are employed to solve the parameter identification problem for six fractional-order chaotic systems. These metaheuristic methods involve Ali Baba and the Forty Thieves (AFT), Chameleon Swarm (CS) method, Artificial Gorilla Troops (AGT) Optimizer, Coot Bird (CB), and Harris Hawks (HH) optimization. Three novel fractional-order chaotic systems, in addition to Borah, Chen, and financial systems, are investigated. The Mean Square Error is used as an objective function to find the optimal parameters and orders of fractional-order chaotic systems. Numerical simulations demonstrate that the Ali Baba and the Forty Thieves (AFT) method achieves greater accuracy with a higher convergence rate for parameter identification problem for four selected fractional-order chaotic systems, while the Artificial Gorilla Troops (AGT) optimizer obtains better numerical and graphical results for two fractional-order chaotic systems compared to other metaheuristic methods.

This paper presents an adaptable method for identifying pedestrian cues. Cue detection is investigated for adults in isolation and groups. The aim is to detect a single cue for each pedestrian. Colour Inverse Maximum Likelihood Ratio (IMLR) criteria are employed to distinguish object and background regions using a mask designed to accommodate a wide range of appearances. The adaptability and specificity of the method is demonstrated using images containing trees and street furniture; structures that are often confused with pedestrians by computer vision systems. Test images of low contrast are also included to assess the sensitivity of the cue detection process. Evaluation with over 250 images gives a false positive error rate of 10% and a false negative error rate of 1.5% % under exacting detection criteria with a complexity of where n is the number of image points considered. The speed of execution is 8 mS per frame for images of 640 by 480 pixels on an Intel core i3-2310MTM CPU running at 2.10GHz with 4.00GB RAM.

This paper discusses the application of artificial neural networks (ANNs) in the area of identification and control of nonlinear dynamical systems. Since chemical processes are getting more complex and complicated, the need of schemes that can improve process operations is highly demanded. ANNs are capable of learning from examples, perform non-linear mappings, and have a special capacity to approximate the dynamics of nonlinear systems in many applications. This paper describe the application of neural network for modeling reactor level, reactor pressure, reactor cooling water temperature, and reactor temperature problems in the Tennessee Eastman (TE) chemical process reactor. The potential of neural network technology in the process industries is great. Its ability to model process dynamics makes it powerful tool for modeling and control processes. A comparison between the applications of ANNs to model the TE plant is compared with other soft computing techniques like fuzzy logic (FL) and adaptive neuro-fuzzy inference systems (ANFIS).
