We present and discuss various manipulation algorithms for HRD, including the basic set-oriented operations, weakest precondition calculation, and normalization. We implemented the ideas and experimented to see their performance. Finally, we have also developed a pruning technique for state-space exploration based on parameter valuation space characterization. The technique showed good promise in our experiment.11 pages, 1 figureData Structures and AlgorithmsLogic in Computer ScienceB.2.2; B.4.4; B.5.2; B.6.3; D.2.4; F.1.1; F.3.1; F.4.1text
