Table . Metrics of optimization consistency for 100 L-BFGS-B optimizations starting from random points within the bounds box for the surrogates produced in each of the 5 𝑁 = 10 "pure-only" optimizations. 𝑆𝐷 𝜒 is standard deviation of resulting minimized objective functions, Δ𝜒 indicates the difference between best and worst objective function, 𝑂 5% indicates the percentage of optimizations within 5% of the best objective for that surrogate, and 𝑁 𝑠𝑖𝑚 indicates number of simulations used to build the optimization.
