Improve difficulty adjustment algorithm

[macterra]

Tesseract currently uses the Dark Gravity Wave difficulty adjustment algorithm, adapted from RavenCoin. It seems to do a decent job of adjusting the difficulty to changes in hashpower but it does display a fair amount of volatility when hashpower remains constant.

It is possible that replacing the algorithm with a discrete PID controller would improve the behavioral characteristics.

Applying a PID controller algorithm to mining difficulty might be a first in the crypto space. Are there small steps we could do to test the concept?

Yes, the first step would be to develop a block mining simulation that could be used to easily test different PID parameters. The effort is likely on the order of a couple days to program a barebones prototype in python.
