comment Find point at which equation stops having roots (if it exists)
The help tells you how to go from the generalised incomplete gamma function to the incomplete gamma function. Then you could just evaluate the integral directly to get the rest. Or many pages (such as mathworld) give the identity for integer arguments.

Or more precisely for b > 6.88164.

Actually you can have roots at negative M values for b > 2.

That's the message indicating that there probably isn't a root. Also, I vote for b = 2.

comment Efficiently filling area with disks located at certain points
Using FindMaximum instead of NArgMax seems lots quicker and gives a similar result. Setting the starting radius to halfway to the closest point makes it even quicker.

comment How can I make the output from Solve look nice?
That polynomial doesn't have nice roots, so I'm not sure what you are expecting. Perhaps Times @@ Roots[...] /. x == r_ -> x - r

comment A Sierpinski-ish structure, via 2D automata
I think removing the r___ in your fruit checking rule should do the trick. Once sorted, the same coordinates should be adjacent in the list. No need to check every possible pair.
