rCMA is a package to perform CMA-ES optimization, using the *Java* implementation by Niko Hansen [Hansen2009].
CMA-ES [HansOst96, Hansen13] is the Covariance Matrix Adapting Evolutionary Strategy for numeric black box optimization.
The main features of rCMA are:
Abiltiy to start the Java CMA-ES optimization with fitness functions defined in R.
Constraint handling: Arbitrary constraints can be incorporated, see function parameter
isFeasible
incmaOptimDP
.Extensibility: Full access to all methods of the Java class
CMAEvolutionStrategy
through packagerJava
. New methods can be added easily. See the documentation ofcmaEvalMeanX
for further details, explanation of JNI types and a full example.Test and Debug: The access of Java methods from R allows for easy debugging and test of programs using
CMAEvolutionStrategy
through R scripts without the necessity to change the underlying JAR file.
The main entry point functions are cmaNew
, cmaInit
and cmaOptimDP
.
Note: To install rJava
properly on some Unix systmes, it might be necessary to issue as
root the command R CMD javareconf
once, or, as normal user to issue the command R CMD javareconf -e
prior to installing package rJava
or prior to loading library rJava
.
