Abstract
The discrete complex Ginzburg­Landau (dCGL) equation describes solitons in multiple waveguide structures. We study,
numerically, its soliton solutions. We compare stability, translational invariance and motion properties for various cases,
including the Ablowitz­Ladik chain, the cubic and two forms of quintic dCGLE.
