libreoffice-nlpsolver 0.9+LibO7.2.6-0ubuntu0.21.10.1~bpo20.04.1 (amd64 binary) in ubuntu focal

 By default LibreOffice Calc ships with a solver engine for linear
 programming only. This allows the optimization of models to a certain degree.
 However, if the formulas or constraints become more complex,
 nonlinear programming is required. That missing gap is now filled by the
 Solver for Nonlinear Programming extension.
 .
 Currently it incorporates two Evolutionary Algorithms which are able to
 handle floating point and integer variables as well as nonlinear constraints.
