    "abstract": "Several techniques have appeared in the literatuare to solve the equations of\ntime-dependent density functional theory. We compare the efficiency of\ndifferent methods based on mesh representations of the wave function (direct\nand Fourier space), taking as a test case the calculation of the surface\nplasmon in the cluster Na_8. For smaller systems, the methods have comparable\nefficiency. For large systems the direct time method has a decided advantage in\ncomputer storage requirements. It is also more economical on arithmetic\noperations, but is not as suited for parallel computing as the methods based on\na frequency representation.",
