Description

ROI_available_solvers returns a data.frame of details corresponding to solvers currently available at one or more repositories. The current list of packages is downloaded over the Internet.

Usage

ROI_available_solvers(x = NULL, method = getOption("download.file.method"))

Arguments

`x`	an object used to select a method. It can be either an object of class `"OP"` or an object of class `"ROI_signature"` or `NULL`.
`method`	a character string giving the method to be used for downloading files. For more information see `download.file`.

To get an overview about the available solvers ROI_available_solvers() can be used. If a signature or an object of class "OP" is provided ROI will only return the solvers applicable the optimization problem. Note since NLP solver are also applicable for LP and QP they will also be listed.

Value

a data.frame with one row per package and repository.

Examples

## Not run: 
ROI_available_solvers()
op <- OP(1:2)
ROI_available_solvers(op)
ROI_available_solvers(OP_signature(op))
