#include <trust_region.h>
DualTrustRegionProblem defines the dual trust region problem given a QuadraticProgram, dual_solution, and dual_gradient. It captures const references to the constructor arguments, which should outlive the class instance. The corresponding trust region problem is max_y dual_gradient^T * (y - dual_solution) s.t. qp.implicit_dual_lower_bounds <= y <= qp.implicit_dual_upper_bounds || y - dual_solution ||_2 <= target_radius where the implicit dual bounds are those given in https://developers.google.com/optimization/lp/pdlp_math#dual_variable_bounds

The objective is negated because the trust region problem objective is minimize, but for the dual problem we want to maximize the gradient.
