Setting lower and upper bounds

[cooo...@gmail.com]

At the start of the Solving section of the docs I see "L and U are lower and upper bounds on the parameter vector x". The docs say that line search methods don't support bounds but do trust region methods? How do I set these bounds?

TIA

So, there were some missing annotations from the Sphinx docs for the bounds methods so they don't appear in the HTML docs, they definitely exist and work for the Trust Region solver.

There is a CL to fix the docs here: https://ceres-solver-review.googlesource.com/5170

If you don't mind looking at the raw sphinx docs, the file you want is src/docs/source/modelling.rst, the main methods are:

Problem::SetParameterLowerBound()

Problem::SetParameterUpperBound()

There is also an example using the bounds in examples/more_garbow_hillstrom.cc
