Choreographies are global descriptions of interactions among
concurrent components, most notably used in the settings of
verification and synthesis of correct-by-construction software. They
require a top-down approach: programmers first write choreographies,
and then use them to verify or synthesize their programs. However,
most software does not come with choreographies yet, which prevents
their application. To attack this problem, previous work investigated
choreography extraction, which automatically constructs a choreography
that describes the behavior of a given set of programs or protocol
We propose a new extraction methodology that improves on the state of the art:
we can deal with programs that are equipped with state and internal
computation; time complexity is dramatically better;
and we capture programs that work by exploiting asynchronous communication.
