Exploration order: layer-based BFS. Considering fixpoint variant with bidirectional inclusion of symbolic zones (instead of equality). Counterexample mode: the analysis will stop as soon as a target state is found. The cartography will be drawn. The result will be written to a file. The trace set(s) will be generated in a graphical mode. Description of states will be output. This model is an L/U-PTA: - lower-bound parameters {delta} - upper-bound parameters {Delta}  Abstract model built after 0.006 second.
