1 .. _chapter-acknowledgements: 2 3 ================ 4 Acknowledgements 5 ================ 6 7 A number of people have helped with the development and open sourcing 8 of Ceres. 9 10 Fredrik Schaffalitzky when he was at Google started the development of 11 Ceres, and even though much has changed since then, many of the ideas 12 from his original design are still present in the current code. 13 14 Amongst Ceres' users at Google two deserve special mention: William 15 Rucklidge and James Roseborough. William was the first user of 16 Ceres. He bravely took on the task of porting production code to an 17 as-yet unproven optimization library, reporting bugs and helping fix 18 them along the way. James is perhaps the most sophisticated user of 19 Ceres at Google. He has reported and fixed bugs and helped evolve the 20 API for the better. 21 22 Since the initial release of Ceres, a number of people have 23 contributed to Ceres by porting it to new platforms, reporting bugs, 24 fixing bugs and adding new functionality. We acknowledge all of these 25 contributions in the :ref:`chapter-version-history`. 26
