Solvers
solve_pwls_pcg
Implements a penalized weighted least square solver using preconditioned conjugate gradient. A penalty object i.e Robject can be used with this solver.
solve_grad_desc
Implements a gradient descent solver without a line search. This is not a practical solver but a pedagogic example of how a solver can be implemented in PowerGrid. We strongly encourage you to use this as a boilerplate template if you wish to implement more complex solvers other than the preconditioned conjugate gradient solver above.
