Abstract: We study the notion of safe realizability for high-level message sequence charts (HMSCs), which was introduced in [2]. We prove that safe realizability is EXPSPACE-complete for bounded HMSCs but undecidable for the class of all HMSCs. This solves two open problems from [2]. Moreover we prove that safe realizability is also EXPSPACEcomplete for the larger class of transition-connected HMSCs. (Update)

...ways, each of which would eliminate the possibility of deadlock. Safe realizability is not entirely captured by closure condition CC3 [18]. This is illustrated by the example scenarios in Figure 7. If we just consider the two MSCs MSC1 and MSC2, the set satisfies CC3. This...
