abstract = "Conventional genetic programming research excludes
memory and iteration. We have begun an extensive
analysis of the space through which GP or other
unconventional AI approaches search and extend it to
consider explicit program stop instructions (T8) and
any time models (T7). We report halting probability,
run time and functionality (including entropy of binary
functions) of both halting and anytime programs. Turing
complete program fitness landscapes, even with halt,
scale poorly.",
