License:	GPL (>= 3)
LazyLoad:	yes

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:

1. Abiltiy to start the Java CMA-ES optimization with fitness functions defined in R.

2. Constraint handling: Arbitrary constraints can be incorporated, see function parameter isFeasible

   in cmaOptimDP.

3. Extensibility: Full access to all methods of the Java class CMAEvolutionStrategy through package list("rJava"). New methods can be added easily. See the documentation of cmaEvalMeanX for further details, explanation of JNI types and a full example.

4. 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.
