There was a problem hiding this comment.
This looks good and works as expected. I just had a minor question about one of the options and comment formatting.

Adds differential evolution for maxwell equation with greedy algorithm used to build ROM.
Example:
build_database phase:
mpirun -np 8 de_parametric_maxwell_greedy -build_database -greedy-param-min 1.0 -greedy-param-max 1.2 -greedy-param-size 5 -greedysubsize 2 -greedyconvsize 3 -greedyrelerrortol 0.01
FOM phase:
mpirun -np 8 de_parametric_maxwell_greedy -visit -fom -f 1.15
DE phase:
mpirun -np 8 de_parametric_maxwell_greedy -f 1.15 -visit -de -de_f 0.9 -de_cr 0.9 -de_ps 50 -de_min_iter 10 -de_max_iter 100 -de_ct 0.001 -de_min_freq 1.0 -de_max_freq 1.2 (Run interpolative differential evolution to see if target FOM can be matched. -visit outputs visualization for vector field with lowest relative error)
Results
Best minimal cost: 1.65478e-05, Best agent: 1.15
