SCIP

This is an R interface to the SCIP Optimization Suite.
SCIP is one of the fastest non-commercial solvers for mixed integer programming (MIP) and mixed integer nonlinear programming (MINLP). It is also a framework for constraint integer programming and branch-cut-and-price. It allows for total control of the solution process and the access of detailed information down to the guts of the solver.

Installation

Install the released version from CRAN:

install.packages("scip")

Or install the development version from GitHub:

# install.packages("pak")
pak::pak("bnaras/scip")

Usage

Refer to the vignettes for examples. However, one of the easiest way to use this and many other solvers is via CVXR (version 1.8.2 and higher).
