(a–d) Visualization of the Branin, McCormick, Camel, and Rastrigin functions in two-dimensional (2D) continuous form. (e–h) Optimization histories across replicates for the Branin, McCormick, Camel, and Rastrigin functions. These plots show the minimal objective function values observed at every iteration. Solid lines represent the median among replicates; shaded areas show plus/minus one MAD. The green dashed lines mark the global minimum value of each function.
