In case anyone is curious, my best solution is currently 14/2488/25.

Optimizing for power, I did it in 21/1292/35.

It took me an entire afternoon to solve this problem. Finally I solved in 28/1.6K/40, which uses 4 MC6000s & 4 ROMs.

My solution is 14 / 4334 / 25.
Though it seemed to be pretty smart, most people did it with much better power usage.

Cool puzzle! Looked impossible at first, but by applying some clever maths, it can be broken down to relatively simple arithmetic.

My current solution is 11/65955/23. I think I can have it 2 yuan cheaper, but I need some sleep first...

I don't think I've ever spent more power on a shenzhen i/o solution than in this puzzle. Running the verification took a rather long time.

My initial solution is 29/235421/60. Yes, that's not a typo, that's 235K power.

Of course, the histograms do seem to indicate that there is a much nicer solution out there...
