config_cs

Create a configuration object for the Cuckoo Search Algorithm (CS). At minimum the number of iterations
(parameter <code>iterations</code>) and the number of host nests (parameter <code>population_size</code>) have
to be provided.

'EmiR' can be used not only for unconstrained optimization problems, but also
in presence of inequality constrains, and variables restricted to be integers.

config_cs function

<dl><dt>iterations</dt>
<dd>maximum number of iterations.</dd>
<dt>population_size</dt>
<dd>number of host nests.</dd>
<dt>iterations_same_cost</dt>
<dd>maximum number of consecutive iterations with the same
(see the parameter <code>absolute_tol</code>) best cost before ending the minimization. If <code>NULL</code> the
minimization continues for the number of iterations specified by the parameter <code>iterations</code>.
Default is <code>NULL</code>.</dd>
<dt>absolute_tol</dt>
<dd>absolute tolerance when comparing best costs from consecutive iterations.
If <code>NULL</code> the machine epsilon is used. Default is <code>NULL</code>.</dd>
<dt>discovery_rate</dt>
<dd>probability for the egg laid by a cuckoo to be discovered by the host bird. It
should be between 0 and 1. Default is <code>0.25</code>.</dd>
