Title: optimParallel: an R Package Providing Parallel Versions of the Gradient-Based Optimization Methods of optim(),
Abstract: The R package optimParallel provides a parallel version of the gradient-based
optimization methods of optim(). The main function of the package is
optimParallel(), which has the same usage and output as optim(). Using
optimParallel() can significantly reduce optimization times. We introduce the R
package and illustrate its implementation, which takes advantage of the lexical
scoping mechanism of R.
