Constructor & Destructor Documentation

Population (  EAEnvironment &    envir, const StringMap &    params )

Standard constructor. Parameters: params  ["autoAdapt"] Should self-adaptation of mutation rates be used? [Default:0] params  ["boolRate"] The mutation rate for BinaryGene genes. params  ["intRate"] The mutation rate for IntGene genes. params  ["floatRate"] The mutation rate for FloatGene genes. params  ["floatVariance"] The mutation variance for FloatGene genes. Parameters: envir  The environment in which the population evolves in. params  Additional dynamic parameters as a String Map. Definition at line 273 of file population.cc. References MutationRate::autoAdaptation(), MutationRate::binaryRate(), MutationRate::doubleRate(), MutationRate::doubleVariance(), MutationRate::intRate(), mAutoadjustGMR, and mGlobalMutationRate.

Member Data Documentation

int mAge [protected]

The number of times the population has been evaluated. Definition at line 89 of file population.h. Referenced by SimplePopulation::getAge(), SimplePopulation::report(), and SimplePopulation::SimplePopulation().

bool mAutoadjustGMR [protected]

Should the global mutation rate be adjusted automatically? Definition at line 99 of file population.h. Referenced by Population().

bool mBasicLog

> Default output stream for extended logs. Definition at line 81 of file population.h.

MutationRate mGlobalMutationRate [protected]
