A Koza-style statistics generator, intended to be easily parseable with awk or other Unix tools. Prints fitness information, one generation (or pseudo-generation) per line. If gather-full is true, then timing information, number of nodes and depths of trees, etc. are also given. No final statistics information is given.
Each line represents a single generation. The first items on a line are always:
Then the following items appear, per subpopulation:
Parameters
base.gather-full bool = true or false (default) |
(should we full statistics on individuals (will run slower, though the slowness is due to off-line processing that won't mess up timings) |
