Bertini Docs Page
Software for solving polynomial systems
Under Linux, Bertini is like any other application. If you drop it in your bin folder, then you can call it as described in the manual. We recommend one folder for each input file, since a number of useful files are generated, and if you use the same folder for multiple input files, you will overwrite output files.
For windows, you need cygwin installed to run Bertini.
The Bertini distribution includes some folders with input files, the user's manual, plus the Bertini executable.
The book Numerical solution of systems of polynomials arising in engineering and science, by A.J. Sommese and C.W. Wampler, is an introduction to Numerical Algebraic Geometry.
