Description:

• The plot shows the cumulative minimum value of all objective function evaluations f(x) at design points x \in D after n iterations, leading to a monotone decreasing function.

Interpretation:

• If the graph shows a decrease, the optimization improves.
  • If the graphs stays (more or less) constant, the optimizer might have converged.

How to use

• ...
• Additional point: If the plot still shows a steep decrease for $n \to n_{max}$, increasing the maximum number of iterations could yield further gain in optimization performance.
