A number of people have helped with the development and open sourcing of Ceres.
Fredrik Schaffalitzky when he was at Google started the development of Ceres, and even though much has changed since then, many of the ideas from his original design are still present in the current code.
Amongst Ceres’ users at Google two deserve special mention: William Rucklidge and James Roseborough. William was the first user of Ceres. He bravely took on the task of porting production code to an as-yet unproven optimization library, reporting bugs and helping fix them along the way. James is perhaps the most sophisticated user of Ceres at Google. He has reported and fixed bugs and helped evolve the API for the better.
Since the initial release of Ceres, a number of people have contributed to Ceres by porting it to new platforms, reporting bugs, fixing bugs and adding new functionality. We acknowledge all of these contributions in the Version History.
