    "abstract": "A system of semi-discrete coupled nonlinear Schr\\\"{o}dinger equations is\nstudied. To show the complete integrability of the model with multiple\ncomponents, we extend the discrete version of the inverse scattering method for\nthe single-component discrete nonlinear Schr\\\"{o}dinger equation proposed by\nAblowitz and Ladik. By means of the extension, the initial-value problem of the\nmodel is solved. Further, the integrals of motion and the soliton solutions are\nconstructed within the framework of the extension of the inverse scattering\nmethod.",
