abstract = {In this AFP entry, we provide a formal implementation of a state-merging technique
to infer extended finite state machines (EFSMs), complete with output and update
functions, from black-box traces. In particular, we define the subsumption in
context relation as a means of determining whether one transition is able to account
for the behaviour of another. Building on this, we define the direct subsumption relation,
which lifts the subsumption in context relation to EFSM level such that we can use it
to determine whether it is safe to merge a given pair of transitions. Key proofs include
the conditions necessary for subsumption to occur and that subsumption and direct subsumption
are preorder relations. We also provide a number of different heuristics which can be used
to abstract away concrete values into registers so that more states and transitions can be
merged and provide proofs of the various conditions which must hold for these abstractions
to subsume their ungeneralised counterparts. A Code Generator setup to create executable
Scala code is also defined.},

abstract = {Models are an important way of understanding software systems. If they do
not already exist, then we need to infer them from system behaviour. Most current
approaches infer classical FSM models that do not consider data, thus limiting
applicability. EFSMs provide a way to concisely model systems with an internal
state but existing inference techniques either do not infer models which allow
outputs to be computed from inputs, or rely heavily on comprehensive white-box
traces that reveal the internal program state, which are often unavailable.
In this paper, we present an approach for inferring EFSM models, including functions
that modify the internal state. Our technique uses black-box traces which only
contain information visible to an external observer of the system. We implemented
our approach as a prototype.},
