TABLE 5. Comparative Search Techniques.

Optimization techniques	Parameters evaluated	The overall time is taken (in Sec)*	Cross-validation score (%)	Test score (%)
Grid Search	6561	10473.740	97.39	98.00
Random Search	30	162.794	97.97	98.10
Bayesian optimization	30	675.389	98.00	98.20
Harris Hawks optimization	200	6204.80	98.39	98.00
*In case of grid search: time is taken to iterate overall parameter combination.
*In case of random search and Bayesian optimization: time is taken to go over a predefined number of iterations (30)
