The Niche Search classes

Here is the whole niche search code.

Ecosystem

A class for holding a set of niches, making them interact and compete

Niche

Handle class for Niches' manipulation

NicheRep

This is the body of the Niche class

NichePars

A simple class for keeping the parameters required by the operations inside Niches: scaling and selection of the fittest individuals

AutoNichePars

A specialisation of NichePars, which forces the selectivity to be small in the beginning, then gradually allowing it to be larger as the number of generations increases (to try to avoid too early convergence)

IndRep

Body class for the Individual class, with reference counting

Individual

Handle class for individuals' manipulation

linear_time

Calculate a value for the time, in [0,1], as a function of the current generation and the total number of generations

sigmoid_time

Calculate a value for the time, in [0,1], as a function of the current generation and the total number of generations

Clock

This class keeps track of the number of generations that have been completed in the system

ControlRep

body class for the ControlPars class, with reference counting

ControlPars

Class to hold the values to control the algorithm, mainly the way that recombination of niches inside the ecosystem is done

BasePars

A base class for all parameters used in niche search, which gives them the possibility of knowing the current generation, and hence make the value of the parameters evolve with time
