Method Details [hide private]

__init__(self, points, crossover_prob=0.1)
(Constructor)

source code 
Initialize to do crossovers at the specified probability.
Overrides: object.__init__

_generate_locs(self, bound)

source code 

Generalized Location Generator:

arguments:

  • bound (int) - upper bound
returns: [0]+x_0...x_n+[bound]
where n=self._npoints-1
and 0 < x_0 < x_1 ... < bound

_crossover(self, x, no, locs)

source code 

Generalized Crossover Function:

arguments:
  • x (int) - genome number [0|1]
  • no (organism,organism)
  • new organisms
  • locs (int list, int list)
  • lists of locations, [0, +n points+, bound] for each genome (sync'd with x)

return type: sequence (to replace no[x])
