subject to the following constraint: subject to the following constraint:

- returns the number of iterations performed. If this method fails to - returns the number of iterations performed. If this method fails to converge
converge to eps accuracy then the number returned will be max_iter+1. to eps accuracy then the number returned will be max_iter+1.
- if this function returns 0 or 1 then we are not hitting the radius bound. - if (this function didn't terminate due to hitting the max_iter iteration limit) then
Otherwise, the radius constraint is active and std::abs(length(#p)-radius) <= eps. - if this function returns 0 or 1 then we are not hitting the radius bound Otherwise,
the radius constraint is active and std::abs(length(#p)-radius)/radius <= eps.
