Paper Abstract

A new look at damped least squares has led to the development of a "smart equation solver" that enables optimization to take place in the least constrained space and to completely prevent singular variables and constraints from destroying the solution. Damping can now be reserved for handling non-linearities - its intended purpose. Reliability has been enhanced and improved speed of convergence is demonstrated in two examples. This lays the foundation for a series of planned future enhancements.
