What is it about?

In the real world, solving complex problems with multiple variables can be challenging for traditional optimization methods. That's why it's crucial to develop efficient and robust techniques to tackle these issues. Computational intelligence (CI) optimization methods, such as swarm intelligence (SI) and evolutionary computation (EC), offer promising alternatives to traditional gradient-based approaches. SI algorithms are inspired by the collective behavior of individuals in a group, while EC algorithms mimic adaptive search inspired by the process of evolution. In this study, we compare SI and EC algorithms, specifically nature-based and human-based algorithms, in the context of water resources planning and reservoir management to optimize reservoir operations. To assess the performance of these algorithms, we applied four optimization methods: particle swarm optimization (PSO), teaching–learning-based optimization algorithm (TLBO), genetic algorithm (GA), and cultural algorithm (CA). Our focus was on optimizing the operation of the Aydoghmoush reservoir in Iran. We evaluated the algorithms based on four criteria: objective function value, run time, robustness, and convergence rate. In terms of the objective function value, the results showed that PSO, TLBO, GA, and CA achieved values of 2.81 × 10–31, 1.66 × 10–24, 4.29 × 10–4, and 1.44 × 10–2, respectively. Overall, both SI and EC algorithms performed well and provided optimal solutions for reservoir operation. However, SI algorithms demonstrated better accuracy, convergence rate, and efficiency in reaching global optima compared to EC algorithms. In conclusion, our study highlights the effectiveness of SI and EC algorithms in optimizing reservoir operations for water resources planning and management. SI algorithms, in particular, showed superior performance in terms of solution accuracy, convergence rate, and runtime. These findings contribute to the development of robust optimization techniques for real-world problems, ensuring more efficient and accurate decision-making in water resource management.

Being the "Idea man" in this project, I was, for the most part, just in the backseat, making sure things were running smoothly! That said, it completely changed my perspective on computational intelligence and its applications in today's research landscape. Witnessing firsthand how these techniques are utilized to solve complex problems was truly eye-opening. It made me realize the immense potential and game-changing impact of computational intelligence, but also its drawback and pitfall. This experience has given me a newfound appreciation for the power of these innovative approaches if they are used in the right context.
