(LaTeX) Abstract:

In this paper we obtain parameterized subexponential-time
algorithms for \kaggLG{} (\kagg{}) --- a problem in social
choice theory --- and for \oscmLG{} (\oscm{}) -- a problem in
graph drawing (see the introduction for definitions). These
algorithms run in time $\Oh^{*}(2^{\Oh(\sqrt{k}\log k)})$, where
$k$ is the parameter, and significantly improve the previous
best algorithms with running times $\Oh^{*}(1.403^k)$ and
$\Oh^{*}(1.4656^k)$, respectively. We also study natural
``above-guarantee'' versions of these problems and show them to
be fixed parameter tractable. In fact, we show that the
above-guarantee versions of these problems are equivalent to a
weighted variant of {\sc $p$-Directed Feedback Arc Set}. Our
results for the above-guarantee version of \kagg{} reveal an
interesting contrast. We show that when the number of ``votes''
in the input to \kagg{} is {\em odd} the above guarantee version
can still be solved in time $O^{*}(2^{\Oh(\sqrt{k}\log k)})$,
while if it is {\em even} then the problem cannot have a
subexponential time algorithm unless
the exponential time hypothesis fails (equivalently, unless FPT$=$M[$1$]).
