class_docstr: Generic solver which *iteratively* solves an equation/optimization problem. Involves an  
  initialization step, the iteration loop body and the termination condition.
docstr: Termination step preparing the return value.
  
  Args:
      arguments: ???
      x: Final solution estimate.
      *args: Additional solver-specific arguments.
  
  Returns:
      Final solution.
