Puzzle 19: Only build at most one robot per round!
After reading the rules more carefully, I see we can only build one
robot per round! (Not just one robot per material type, one robot!) Doh!
This reduces the combinatorial explosion a lot. The exhaustive search
has become a lot more feasible, with Blueprint 2 of the test input able
to cover 22 rounds in a minute and a half. I shouldn't only need to find
some small wins from here to get the 24-round runtime to something
sensible.
