Rate > Cost > Instructions
Area > Cycles > Cost
The Rate metric waits for a solution to enter a repeating steady state, then compares solutions by the length of the repeat period divided by the number of outputs produced during that period. For example, a solution that outputs 3 times in every 12 cycle period (rate 4) is considered better, according to the Rate metric, than a solution that outputs 2 times in every 10 cycle period (rate 5). Solutions which don't enter a repeating steady state are not considered for the Rate metric.
So if we arrange them into this shape—
Ah, like the classic radio receiver crystals we used to make at school!
Yes, but see how the structure changes here—
And in theory, this will work at any distance?
If our last measurements were accurate. I'm still trying to wrap my head around it myself.
If only we could do more than just send signals…
There's nothing we've seen so far that would stop us from going further. But actually working out the details… seems challenging.
