[<code>ecr_optimization_task</code>]
Optimization task. If a <code>smoof_function</code> is passed it is automatically
converted into a task.

task

[<code>numeric(1)</code>]
Mutation probability for bitplip mutation.
Default is $1/n$ where n is the length of the gene.

[<code>integer(1)</code>]
Maximal number of iterations. Default ist <code>100L</code>.

max.iter

[<code>integer(1)</code>]
Maximal number of iterations/generations. Default is <code>Inf</code>.

max.evals

[<code>integer(1)</code>]
Time budget in seconds. Default ist <code>Inf</code>.

max.time

The simplest evolutionary algorithm one can imagine, namely the (1+1) EA/GA.
Maintains a population of a single individual x and uses just bitplip mutation
to generate a child y (obviously no recombination takes place), i.e., each gene
of x is flipped with probability <code>p</code> independently. The best individual
survives.
This algorithm is of particular interest in the theory of evolutionary algorithms
and its performance is well understood for different function families.
A lot of interesting results exist.


optimize

Provides a powerful framework for evolutionary
computing in R. The user can easily construct powerful evolutionary algorithms
for tackling both single- and multi-objective problems by plugging in different
predefined evolutionary building blocks, e. g., operators for mutation,
recombination and selection with just a few lines of code. Your problem
cannot be easily solved with a standard EA which works on real-valued vectors,
permutations or binary strings? No problem, 'ecr' has been developed with that in
mind. Extending the framework with own operators is also possible. Additionally
there are various comfort functions, like monitoring, logging and more.
