xegaPopulation (version 1.0.0.11)

xegaObservePopulation: Observe summary statistics of the fitness of the population.

Description

xegaObservePopulation() reports summary statistics of the fitness of the population.

Usage

xegaObservePopulation(fit, v = vector())

Value

Vector of population statistics. If position

x modulo 8 equals

1. 1: Mean fitness.

2. 2: Min fitness.

3. 3: Lower-hinge (approx. 1st quartile) of fitness.

4. 4: Median fitness.

5. 5: Upper-hinge (approx. 3rd quartile) of fitness.

6. 6: Max fitness.

7. 7: Variance.

8. 8: Mean absolute deviation.

Arguments

fit

Vector of fitness values of a population.

v

Vector of population statistic vectors.

Details

Population statistics are used for

• implementing individually variable operator rates and

• visualizing the progress of the algorithm.
