In 2013, Galtier et al. [1] have revisited theoretically a numerical trick that had been used since the very beginning of linear-transport Monte-Carlo simulation: introducing virtual absorbers or scatterers into a heterogeneous field to make it "look" homogeneous. Webriefly describe some reported and ongoing researches that were initiated by this theoretical work and we try to classify them by proposing three alternative viewpoints on the very same null-collision concept.
