Key Points

To formulate and evaluate an Enhanced Moss Growth Optimization (EMGO) framework designed to improve exploratory step-size control and local covariance exploitation in complex, high-dimensional engineering tasks.
Integrated a budget-adaptive jump regulation mechanism and a shrinkage-regularized covariance-guided sampling operator with relative eigenvalue flooring into the baseline MGO algorithm.
Benchmarked EMGO against 10 state-of-the-art optimizers (including CMA-ES, L-SHADE, and SBO) across 29 CEC2017 functions in 50 and 100 dimensions over 30 runs with 300,000 evaluations per run.
Tuned support vector regression (SVR) hyperparameters to predict effluent suspended solids using the UCI Water Treatment Plant dataset via rolling-origin cross-validation and SHAP interpretability analysis.
EMGO demonstrated statistically significant performance gains across 50- and 100-dimensional CEC2017 functions evaluated via nonparametric Friedman ranking and Holm-adjusted Wilcoxon signed-rank tests.
In wastewater effluent suspended solid prediction, EMGO-SVR attained an RMSE of 5.58 ± 0.64, MAE of 3.97 ± 0.46, and R2 of 0.889 ± 0.028, outperforming standard SVR, tree-based ensembles, and Bayesian optimization.
