The dynamical properties of many-dimensional solitons in the framework of the Klein-Gordon equation with logarithmic nonlinearity have been studied by means of the computer simulations. The existence of the same types of soliton interactions found earlier in the framework of the Klein-Gordon equation with saturable nonlinearity is displayed. It means that the types of soliton interaction are model independent. Some details of the numerical simulation techniques are discussed.
