+In this chapter we will describe the various classes that are part of
+Ceres Solver's modeling API, and how they can be used to construct
+optimization.
+
+Once a problem has been constructed, various methods for solving them
+will be discussed in :ref:`chapter-solving`. It is by design that the
+modeling and the solving APIs are orthogonal to each other. This
+enables easy switching/tweaking of various solver parameters without
+having to touch the problem once it has been successfuly modeling.
