Currently there is a bug in the copy constructor of ExpressionRef.
Fixing this bug, will create new expressions each time a copy is
executed. To reduce the amount of copy expression we pass
ExpressionRef by const reference now.

Ceres Solver

Ceres Solver is an open source C++ library for modeling and solving large, complicated optimization problems. It is a feature rich, mature and performant library which has been used in production at Google since 2010. Ceres Solver can solve two kinds of problems.

  1. Non-linear Least Squares problems with bounds constraints.
  2. General unconstrained optimization problems.
