sci@gentoo.org Gentoo Science Project Ipopt is a 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). hsl Enable sci-libs/mumps support
