Applications are made for Sawada-Kotera and a (2+1)-dimensional equations, thereby presenting their N-wave solutions. An opposite question is also put forward and discussed about generating Hirota bilinear equations possesses the indicated N-wave solutions and a few illustrative examples are presented, together with an algorithm using weights. %K Hirota Bilinear Form %K Soliton Equations %K N-Wave Solution %U http://article.sapub.org/10.5923.j.ajcam.20130301.02.html
