Description Usage Arguments Value Recombination Parameters References

View source: R/recombination_blxAlphaBeta.R


Implements the "/blxAlphaBeta" (Blend Alpha Beta) recombination for the ExpDE framework





population matrix (original)


population matrix (mutated)


recombination parameters (see Recombination parameters for details)


Matrix U containing the recombined population

Recombination Parameters

The recpars parameter contains all parameters required to define the recombination. recombination_blxAlpha() understands the following fields in recpars:

  • alpha : extrapolation parameter for 'best' parent vector.
    Accepts real value 0 <= alpha <= 0.5.

  • beta : extrapolation parameter for 'worst' parent vector.
    Accepts real value 0 <= beta <= 0.5.

@section Warning: This recombination operator evaluates the candidate solutions in M, which adds an extra popsize evaluations per iteration.
