In this particular case, if you were to iterate over all possible

time is order N instead of order N^2.
The problem with the exhaustive search is there are 2^17 = 131,072
combinations to try. (256 cap and inductor values, plus reversing the
whole L network)
It takes a few ms for each relay to physically switch. If you can try
100 combinations a second (10 ms), that's still about 20 minutes to
try them all. Even with 1 ms switching time, you're still looking at
2 minutes to find a match.
A tough problem.
