Description

Start with a very high regularizer, so the problem is easy to solve, and decrease it. Each iteration should be very fast. Design `make_prox_*` so that changing lambda incurs little overhead. Allow user to choose lambda_min and lambda_max, but also include good defaults to encourage interesting (eg non-zero) solutions.

Research direction

Start by locating the `make_prox_*` entry points and reading how regularization parameters are currently passed through the solver. Clarify the intended lambda range and defaults with the maintainers; done means users can choose `lambda_min` and `lambda_max`, receive useful defaults, and run successive regularization iterations with little lambda-change overhead.
