mutDoubleGeom

mutDoubleGeomScaled

<code>[integer]</code> individual to mutate.

<code>[numeric(1)]</code> per-entry probability to perform mutation.

<code>[numeric]</code> geometric distribution parameter.

geomp

<code>[integer]</code> lower bounds of <code>ind</code> values. May have same length as
<code>ind</code> or may be a single number, if the lower bounds are the same for all
values.

lower

<code>[integer]</code> upper bounds of <code>ind</code> values. May have same length as
<code>ind</code> or may be a single number, if the upper bounds are the same for all
values.

upper

<code>[numeric]</code> standard deviation, relative to <code>upper - lower</code>.

sdev

"Double Geometric" mutation operator for integer parameters: with
probability <code>p</code> a random geometrically distributed value is added,
and another (different) one subtracted.
<code>mutDoubleGeomScaled</code> scales <code>sdev</code> with each component's range and then uses
<code>geomp = (sqrt(2 * sdev^2 + 1) - 1) / sdev^2</code>.

Performs simultaneous hyperparameter tuning and
feature selection through both single-objective and multi-objective
optimization as described in Binder, Moosbauer et al. (2019) <arXiv:1912.12912>.
Uses the 'ecr'-package as basis but adds mixed integer
evolutionary strategies and multi-fidelity functionality as well as operators
specific for the problem of feature selection.
