We are concerned with difference approximation of scalar conservation laws. The convergence of approximate solution obtained by difference approximation is one of the main interests in the theory of difference approximation. We discuss the range of numerical viscosity coefficients that arrows the convergence to the entropy solution in the case of 3-stencil difference scheme in conservation form. The main theorem is one of the most optimal results of this kind of discussion. The aim of report is to explain the main theorem and related things from the viewpoint of numerical computation.
