#include <triqs/experimental/lattice/bz_integrators.hpp>

Detailed Description

Options controlling the combined PTR and adaptive Brillouin-zone integration.

The integration first attempts to converge each frequency with fixed k-grid (PTR) integration of increasing grid density, starting from k_grid and increasing in steps of delta_k_grid until a point converges or the grid reaches k_grid_max. The remaining unconverged frequency points are then integrated adaptively until they reach the requested absolute tolerance.
