effective population size low when re-spawning in NERO #66

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago
debugging information reports very low effective population sizes when 
re-spawning NERO organisms:

[ai] Effective rtNEAT population of size: 6, min. fitness: 0, max. fitness: 
1.06782
[ai] Effective rtNEAT population of size: 5, min. fitness: 0, max. fitness: 
1.06782
[ai] Effective rtNEAT population of size: 4, min. fitness: 0, max. fitness: 
1.06782
[ai] Effective rtNEAT population of size: 3, min. fitness: 0, max. fitness: 
1.06782

after a large re-implementation effort, the rtNEAT object now closely mimics 
what was happening in NERO 1.1 and NERO 2.0, which allows the organisms to 
persist across several lifetimes and their fitness to be averaged across those.

See RTNEATFactoryDesign for more details.
