We introduce a general model of a one-dimensional dynamical lattice with the on-site cubic nonlinearity and both nearest-neighbor (NN) and next-nearest-neighbor (NNN) linear interactions between lattice sites (i.e., a generalized discrete nonlinear Schrödinger equation). Unlike some previously consi
