Overview

About

Maintained by Andrea Giusto1 releasesCRAN page ↗

Active set method solver for the solution of indefinite quadratic programs, subject to lower bounds on linear functions of the variables and simple bounds on the variables themselves. The function QPmin() implements an algorithm similar to the one described in Gould (1991) doi:10.1093/imanum/11.3.299 with the exception that an efficient sparse internal representation of the basis matrix is maintained thus allowing the solution of somewhat large problems.

Install

R (source archive)Ubuntu (r2u)openSUSE (OBS)

url <- "https://cran.r-project.org/src/contrib/Archive/QPmin/QPmin_0.5-1.tar.gz"
pkgFile <- "QPmin_0.5-1.tar.gz"
download.file(url, pkgFile)
install.packages(pkgFile, type = "source", repos = NULL)

This package is no longer on CRAN, so install.packages() cannot fetch it by name. This downloads the last archived source (0.5-1) and builds it locally. Install its dependencies first, and note that building from source needs the usual compiler toolchain.

Release

# enable cranapt (r2u) if it is not already set up, then install
grep -rqs r2u.stat.illinois.edu /etc/apt/sources.list /etc/apt/sources.list.d/ \
  || curl -fsSL https://raw.githubusercontent.com/eddelbuettel/r2u/master/inst/scripts/add_cranapt_noble.sh | sudo bash
sudo apt install -y r-cran-qpmin

Fast Ubuntu binaries via r2u (no compilation). The cranapt setup runs once and is skipped when it is already enabled.

bspm (used by r2u) also needs make: sudo apt install make

# add the autoCRAN OBS repo (Tumbleweed) if it is missing, then install
zypper -q lr | grep -qi autoCRAN \
  || sudo zypper addrepo https://download.opensuse.org/repositories/devel:/languages:/R:/autoCRAN/openSUSE_Tumbleweed/devel:languages:R:autoCRAN.repo
sudo zypper install -y R-QPmin

RPMs auto-built from CRAN on openSUSE OBS (Tumbleweed).
