  3. Added the ability to get the "worst" individual from a population.

    Kind of strange, I know, but sometimes you just want to make sure
    that your best individual really is something special. An easy way
    to do this is to compare it against the worst individual.

    Merge pull request #11 from booherbg/master

    Merging the pull request from Blaine, adding the Gradient Gaussian mutators, we should change this later to adapt the older mutation methods.

  1. added some additional references to SBX crossover

  2. Added GaussianGradient mutator which is useful for mutations that are…

    … relative
    to the gene, not absolute like it currently is.
    Default mean = 1.0
    Default std = 0.0333
    This means that the values will be multiplied by 1.0 with a std of 0.0333. In
    other words, 68% of the time, the multiplier will be within +/- 0.999 (10%) of
    the gene value.

  1. Added support for a new mutator similar to Gaussian but called Gaussi…

    The following four mutators are new:
    The main difference between Gaussian and GaussianGradient is that
    GaussianGradient uses a multiplicative modification rather than an additive.
    GaussianGradient's mu and sigma are absolute, not relative. So if the default
    values of mu=2 and std=10 (why not mu=0?) are used, the random gaussian number
    is a flat number around 2. If we're working on a huge range, like say 0-100000,
    this is a very small drift.
    GaussianGradient uses mu=1.0 and std=0.1 to generate a number around 1.0. This
    is then *multiplied* by the gene to provide subtle drift regardless of how
    large the range is.
    2 new constants added, Mu and Sigma for the GaussianGradient routines.

    Support for MPI. We will need to remove the host/port requirement from the MigrationScheme, so we can inherit MigrationScheme frmo the new MPI scheme.
