Grasshopper Optimization Algorithms in Engineering Applications

Grasshopper Optimization Algorithms (GOAs) are a class of swarm-inspired metaheuristics modelled on the collective foraging behaviour of grasshopper swarms. Since its inception, GOA has been applied to a wide array of engineering problems, from energy management and structural design to power quality control and predictive modelling. The core principle involves agents dynamically adjusting their positions under social attraction and repulsion forces, guided by a control parameter that decreases over time to shift from exploration to exploitation. While the original GOA offers simplicity and adaptability, it can suffer from slow convergence and entrapment in local optima. In response, researchers have developed enhanced variants—incorporating mechanisms such as chaotic maps, nonlinear coefficients, Levy flights and hybrid local-search strategies—to achieve faster convergence, higher precision and robust global search. These advancements have enabled practical implementations in smart grids, motor drives, scheduling and hybrid filter design, delivering improvements in efficiency, accuracy and cost effectiveness.

Recent studies have integrated a Levy flight mechanism into the standard GOA framework to produce an improved version that better balances local refinement and global exploration. This enhancement has demonstrated superior performance across mathematical benchmarks and a range of real-world engineering tasks, evidencing high convergence speed and precision. Parallel efforts have introduced gravitational and inertial dynamics into position-update rules, yielding an algorithm with accelerated convergence and reduced sensitivity to initial conditions. This variant has been effectively coupled with neural network models to optimise parameters for predictive applications, such as air quality forecasting and financial time-series prediction, showcasing its versatility in both design and modelling contexts.

Several recent contributions have addressed the original GOA’s limitations through multi-strategy frameworks. One approach employs population initialization via circle mapping, nonlinear decreasing coefficients, golden sine updates, greedy selection and quasi-reflection learning to escape local optima; this algorithm outperforms predecessors on classical engineering design benchmarks. In smart grid management, novel GOA variants combine grouping of control parameters with mutation operations to schedule residential, commercial and industrial loads, achieving substantial reductions in peak demand and operating cost. Another line of work couples grasshopper optimisation with neural-based active filtering for three-phase induction motors, optimising filter parameters to suppress harmonic distortion and enhance power-quality metrics with minimal computational overhead.
