Bases: SimPEG.objective_function.ComboObjectiveFunction

class similar to regularization.tikhonov.Simple, with a PGIsmallness. PARAMETERS ———- :param SimPEG.utils.WeightedGaussianMixture gmmref: refereence/prior GMM :param SimPEG.utils.WeightedGaussianMixture gmm: GMM to use :param SimPEG.maps.Wires wiresmap: wires mapping to the various physical properties :param list maplist: list of SimPEG.maps for each physical property. :param discretize.BaseMesh mesh: tensor, QuadTree or Octree mesh :param boolean approx_gradient: use the L2-approximation of the gradient, default is True :param boolean approx_eval: use the L2-approximation evaluation of the smallness term
