However until now, there is no general theory of acceleration, and designing acceleration algorithms for new data types is a complex task. On the other hand, protocols rarely manipulate new data types, rather new combinations of well-studied data types. For this reason, in this paper we focus on the automatic construction of symbolic representations and acceleration algorithms from existing ones. \itemrv{~} \itemcc{} \itemut{reachability set; unbounded heterogeneous data; composition of symbolic representations and acceleration methods} \itemli{doi:10.1007/b102065} \end
