Interior-Point Optimizer, for large-scale nonlinear optimization
Ipopt is an open-source solver for large-scale nonlinear continuous optimization. It can be used from modeling environments, such as AMPL, GAMS, or Matlab, and it is also available as a callable library with interfaces to C++, C, and Fortran. Ipopt uses an interior point method, together with a filter linear search procedure. Ipopt is part of the larger COIN-OR initiative (Computational Infrastructure for Operations Research). The Debian package is compiled against MUMPS (as it is the only one of the avaialble solvers that is Free Software and inculded in Debian). This package contains the library.
More information about apt-get remove
Advanced Package Tool, or APT, is a free software user interface that works with core libraries to handle the installation and removal of software on Debian, Ubuntu and other Linux distributions. APT simplifies the process of managing software on Unix-like computer systems by automating the retrieval, configuration and installation of software packages, either from precompiled files or by compiling source code.
apt-get is the command-line tool for handling packages, and may be considered the user's "back-end" to other tools using the APT library.
apt-get remove is identical to install except that packages are removed instead of installed. Note that removing a package leaves its configuration files on the system. If a plus sign is appended to the package name (with no intervening space), the identified package will be installed instead of removed.
