Release of optimbase, optimsimplex and neldermead packages
...algorithms based on the simplex method. The
provided algorithms are direct search algorithms, i.e. algorithms which do
not use the derivative of the cost function. They are based on the update of
a simplex. The following algorithms are available: the fixed size simplex
method of Spendley, Hext and Himsworth (unconstrained optimization with a
fixed sized simplex), the variable size simplex method of Nelder and Mead
(unconstrained optimization with a variable sized simplex), Box's complex
method (constrained optimization with a variable sized simplex). This
package includes an R-port of the fminsear...

CRAN (and crantastic) updates this week
...based on the
simplex method. The provided algorithms are direct search
algorithms, i.e. algorithms which do not use the derivative of the
cost function. They are based on the update of a simplex. The
following algorithms are available: the fixed shape simplex method
of Spendley, Hext and Himsworth (unconstrained optimization with a
fixed shape simplex), the variable shape simplex method of Nelder
and Mead (unconstrained optimization with a variable shape simplex
made), and Box's complex method (constrained optimization with a
variable shape simplex).
