Higher-Order Pushdown Systems with Data
We propose a new extension of higher-order pushdown automata, which allows to use an infinite alphabet. The new automata recognize languages of data words (instead of normal words), which beside each its letter from a finite alphabet have a data value from an infinite alphabet. Those data values can be loaded to the stack of the automaton, and later compared with some farther data values on the...
متن کاملInfinite Games over Higher-Order Pushdown Systems
In this thesis we deal with games over infinite graphs with regular winning conditions. A well studied family of such games are the pushdown games. An important result for these games is that the winning region can be described by regular sets of configurations. We extend this result to games defined by higher-order pushdown systems. The higher-order pushdown systems extend the usual pushdown s...
متن کاملSymbolic Backwards-Reachability Analysis for Higher-Order Pushdown Systems
Higher-order pushdown systems (PDSs) generalise pushdown systems through the use ofhigher-order stacks, that is, a nested “stack of stacks” structure. These systems may be usedto model higher-order programs and are closely related to the Caucal hierarchy of infinitegraphs and safe higher-order recursion schemes.We consider the backwards-reachability problem over higher-order Alt...
متن کاملGlobal Model-Checking of Higher-Order Pushdown Systems
Pushdown systems equip a finite state system with an unbounded stack memory, and are thus infinite state. By recording the call history on the stack, these systems provide a natural model for recursive procedure calls. Model-checking for pushdown systems has been well-studied. The most successful implementation of these techniques is the tool Moped, which has become an important component of ve...
متن کاملThe Complexity of Model Checking (Collapsible) Higher-Order Pushdown Systems
We study (collapsible) higher-order pushdown systems — theoretically robust and wellstudied models of higher-order programs — along with their natural subclass called (collapsible) higher-order basic process algebras. We provide a comprehensive analysis of the model checking complexity of a range of both branching-time and linear-time temporal logics. We obtain tight bounds on data, expression,...
