Exploration order: layer-based BFS. Considering fixpoint variant with bidirectional inclusion of symbolic zones (instead of equality). Merging technique of [AFS13] enabled. 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.
