#49 Most Permissive Boolean Networks with Loïc Paulevé

Listen Later

In systems biology, Boolean networks are a way to model interactions such as

gene regulation or cell signaling. The standard
interpretations of Boolean networks are the synchronous, asynchronous, and
fully asynchronous semantics.

In this episode, Loïc Paulevé explains how the

same Boolean networks can be interpreted in a new, “most permissive” way.
Loïc proved mathematically that his semantics can reproduce all behaviors
achievable by a compatible quantitative model, whereas the
traditional interpretations in general cannot. Furthermore, it turns out that
deciding whether a certain state in a Boolean network is reachable can be done
much more efficiently in MPBNs than in the traditional interpretations.
