  We analyze Lindblad-Gorini-Kossakowski-Sudarshan-type generators for selected
periodically driven open quantum systems. All these generators can be obtained
by temporal coarse-graining procedures, and we compare different
coarse-graining schemes. Similar to for undriven systems, we find that a
dynamically adapted coarse-graining time, effectively yielding non-Markovian
dynamics by interpolating through a series of different but invididually
Markovian solutions, yields the best results among the different
coarse-graining schemes, albeit at highest computational cost.
