We present a polynomial-time algorithm deciding bisimilarity between a normed BPA process and a normed BPP process. This improves the previously known exponential upper bound by Černá, Křetínský, Kučera (1999). The algorithm relies on a polynomial bound for the “finite-state core” of the transition system generated by the BPP process. The bound is derived from the “prime form” of the underlying BPP system (where bisimilarity coincides with equality); we suggest an original algorithm for the respective transformation.
