  The Alon-Tarsi number of a polynomial is a parameter related to the exponents
of its monomials. For graphs, their Alon-Tarsi number is the Alon-Tarsi number
of their graph polynomials. As such, it provides an upper bound on their choice
and online choice numbers. In this paper, we obtain the Alon-Tarsi number of
some complete multipartite graphs, line graphs of some complete graphs of even
order, and line graphs of some other regular graphs.
