Configuration for the column generation solver.
Fields§
§max_iter: usizeMaximum number of column generation iterations.
tol: f64Optimality tolerance for reduced-cost check.
stabilization_rho: f64Proximal stabilisation parameter ρ for the dual ascent. Set to 0.0 to disable stabilisation.
max_columns_per_iter: usizeMaximum number of columns added per pricing call.
dual_step_size: f64Step size for dual ascent gradient steps.
dual_max_iter: usizeMaximum dual ascent iterations per RMP solve.
