Powell:\n\n* `COBYLA` (Powell, 1994) accounts for general inequality constraints.\n\n* `NEWUOA` (Powell, 2006) is for unconstrained optimization.\n\n* `BOBYQA` (Powell, 2009) accounts for bound constraints on the variables.\n\nThis package is a wrapper over the implementations of these algorithms in the C\nlanguage in [`OptimPack`](https://github.com/emmt/OptimPack) libraries. Precompiled\nversions of these libraries are provided by\n[`OptimPack_jll`](https://github.com/JuliaBinaryWrappers/OptimPack_jll.jl)\npackage.\n\nFor a more mature interface to M.J.D. Powell algorithms, I strongly recommend to use the [`PRIMA`](https://github.com/libprima/PRIMA.jl) package.\n\n\n## Installation\n\nThe easiest way to install `PowellMethods` is via Julia registry\n[`EmmtRegistry`](https://github.com/emmt/EmmtRegistry):\n\n```julia\nusing Pkg\npkg\"registry add General\"  # if not yet any registries\npkg\"registry add https://github.com/emmt/EmmtRegistry\"\npkg\"add PowellMethods\"\n```\n\n## References\n\n* M.J.D.
