We are happy to announce the release of the new version of DEoptim
(version 2.0-0) which is now available from CRAN.
The DEoptim package  performs Differential Evolution (DE) minimization,
a genetic algorithm-based optimization technique [2,3]. This allows robust
minimization over a continuous (bounded or not) domain.
The new DEoptim function calls a C implementation of the DE algorithm
similar to the MS Visual C++ v5.0 implementation distributed with .
More details on DE optimization can be found on the DE homepage .
We believe that the DE approach may be applicable in many fields of
research and hope that the package DEoptim will be fruitful for many

o The R-based implementation of Differential Evolution has been
replaced with a C-based implementation similar to the MS Visual C++
v5.0 implementation accompanying the book `Differential Evolution -
A Practical Approach to Global Optimization',downloaded from
The new C implementation is significantly faster.
o The S3 method for plotting has been enhanced. It allows now to plot
the intermediate populations if provided.
o The package maintainer has been changed to Katharine Mullen,
<katharine.mullen at nist.gov>.
o A NAMESPACE has been added.
o Argument FUN for DEoptim is now called fn for compatibility with
o demo file has been removed
o CITATION file modified
