+We have implemented \in{Algorithms}[alg:increase-k, alg:increase-k-v3] in Go, and we have compared their running time on two sets of FSMs.
+\footnote{Available at \todo{https://gitlab.science.ru.nl/rick/partition/}.}
+The first set is from \cite{Smeenk}, where FSMs for embedded control software were automatically constructed.
+These FSMs are of increasing size, varying from 546 to 3~410 states, with 78 inputs and up to 151 outputs.
+The second set is inferred from \citet[Hopcroft1971], where two classes of finite automata, $A$ and $B$, are described that serve as a worst case for \in{Algorithms}[alg:increase-k, alg:increase-k-v3] respectively.
+The FSMs that we have constructed for these automata have 1 input, 2 outputs, and $2^2$~--~$2^{15}$ states.
+The running times in seconds on an Intel Core i5-2500 are plotted in \in{Figure}[fig:results].
+We note that different slopes imply different complexity classes, since both axes have a logarithmic scale.

+  [title={Conclusion}]
+
+In this paper we have described an efficient algorithm for constructing a set of minimal-length sequences that pairwise distinguish all states of a finite state machine.
+By extending Hopcroft's minimisation algorithm, we are able to construct such sequences in $\bigO(m \log n)$ for a machine with $m$ transitions and $n$ states.
+This improves on the traditional $\bigO(mn)$ method that is based on the classic algorithm by Moore.
+As an upshot, the sequences obtained form a characterisation set and a separating family, which play a crucial in conformance testing.
+
+Two key observations were required for a correct adaptation of Hopcroft's algorithm.
+First, it is required to perform splits in order of the length of their associated sequences.
+This guarantees minimality of the obtained separating sequences.
+Second, it is required to consider nodes as a candidate before any one of its children are considered as a candidate.
+This order follows naturally from the construction of a splitting tree.
+
+Experimental results show that our algorithm outperforms the classic approach for both worst-case finite state machines and models of embedded control software.
+Applications of minimal separating sequences such as the ones described by \citet[dorofeeva2010fsm, Smeenk] therefore show that our algorithm is useful in practice.
