__cmp__ ( self,  other )

Define comparisons for organisms.

Compare organisms by their genomes.

__init__ (
        self,
        genome,
        fitness_calculator,
        start_fitness=None,
        )

Initialize an organism

Arguments:

• genome -- A MutableSeq object representing the sequence of the genome.

• fitness_calculator -- A funtion that will calculate the fitness of the organism when given the organisms genome.

• start_fitness - the starting fitness corresponding with the given genome. If not supplied, the fitness will be calculated using fitness_calculator.

__str__ ( self )

Provide a string output for debugging.

copy ( self )

Return a copy of the organism.

This makes it easy to duplicate an organism before changing it.

recalculate_fitness ( self )

Calculate and reset the fitness of the current genome

This should be called after the genome is updated to ensure that fitness always stays in sync with the current genome.
