java.lang.Object | +--ec.Statistics | +--ec.gp.koza.KozaShortStatistics
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.file String (a filename), or nonexistant (signifies stdout) |
(the log for statistics) |
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) |

Method Summary | |
protected void |
_postEvaluationStatistics(EvolutionState state)
Prints out the statistics, but does not end with a println -- this lets overriding methods print additional statistics on the same line |
void |
postBreedingStatistics(EvolutionState state)
Called immediately after breeding occurs. |
void |
postEvaluationStatistics(EvolutionState state)
Called immediately after evaluation occurs. |
void |
postInitializationStatistics(EvolutionState state)
Called immediately after population initialization occurs. |
void |
preBreedingStatistics(EvolutionState state)
Called immediately before breeding occurs. |
void |
preEvaluationStatistics(EvolutionState state)
Called immediately before evaluation occurs. |
void |
preInitializationStatistics(EvolutionState state)
Called immediately before population initialization occurs. |
void |
setup(EvolutionState state,
Parameter base)
Sets up the object by reading it from the parameters stored in state, built off of the parameter base base. |
