Method Summary

double	calculateMortality(int age, double fitness, double saturation) Method to calculate the mortality for an organism of a given age and fitness in an environment.
boolean	isMarked(double mortality)

Method Detail

calculateMortality

double calculateMortality(int age,
                          double fitness,
                          double saturation)

Method to calculate the mortality for an organism of a given age and fitness in an environment.

Parameters:

age - the age of the organism in generations.

fitness - the fitness of the organism for an environment.

saturation - a measure of the current population saturation (1 corresponds to the ideal population supportable by the environment.

Returns:

the probability of death before the next generation (between 0 and 1). TODO consider inlining this into isMarked (ie. pass in age, fitness, saturation, and return boolean)

isMarked

boolean isMarked(double mortality)

Parameters:

mortality - the probability that an organism will die before the next generation (a value between 0 and 1).

Returns:

true if that organism is actually marked for death (i.e. if the mortality value exceeds the current threshold)
