      7 Ceres Solver grew out of the need for general least squares solving at
      8 Google. In early 2010, Sameer Agarwal and Fredrik Schaffalitzky
      9 started the development of Ceres Solver. Fredrik left Google shortly
     10 thereafter and Keir Mierle stepped in to take his place. After two
     11 years of on-and-off development, Ceres Solver was released as open
     12 source in May of 2012.

     14 Origin of the name

     17 While there is some debate as to who invented the method of Least
     18 Squares [Stigler]_, there is no debate that it was `Carl Friedrich
     19 Gauss
     20 <http://www-groups.dcs.st-and.ac.uk/~history/Biographies/Gauss.html>`_
     21 who brought it to the attention of the world. Using just 22
     22 observations of the newly discovered asteroid `Ceres
     23 <http://en.wikipedia.org/wiki/Ceres_(dwarf_planet)>`_, Gauss used the
     24 method of least squares to correctly predict when and where the
     25 asteroid will emerge from behind the Sun [TenenbaumDirector]_. We
     26 named our solver after Ceres to celebrate this seminal event in the
     27 history of astronomy, statistics and optimization.
