  Antifragility is a property from which systems are able to resist stress and
furthermore benefit from it. Even though antifragile dynamics is found in
various real-world complex systems where multiple subsystems interact with each
other, the attribute has not been quantitatively explored yet in those complex
systems which can be regarded as multilayer networks. Here we study how the
multilayer structure affects the antifragility of the whole system. By
comparing single-layer and multilayer Boolean networks based on our recently
proposed antifragility measure, we found that the multilayer structure
facilitated the production of antifragile systems. Our measure and findings
will be useful for various applications such as exploring properties of
biological systems with multilayer structures and creating more antifragile
engineered systems.
