mutUniformParametric

mutUniformParametricScaled

mutUniformParametricInt

mutUniformParametricIntScaled

Adds a variable <code>delta</code> to each component <code>ind[i]</code>
with probability <code>p</code>, where <code>delta</code> is uniformly
distributed between <code>pmax(lower - ind[x], -lx/2)</code> and
<code>pmin(upper - ind[i], lx/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.
