Considering all scenarios with up to 4 observed variables, which number in the thousands, we are able to resolve all but three causal scenarios, providing evidence that the HLP condition is, in fact, exhaustive.

Directed acyclic graphs (DAGs) with hidden variables are often used to characterize causal relations between variables in a system.

Causality is a seminal concept in science: Any research discipline, from sociology and medicine to physics and chemistry, aims at understanding the causes that could explain the correlations observed among some measured variables.

We prove that inflation is asymptotically tight, i. e., that the hierarchy converges to a zero-error test for causal compatibility.

We describe an algorithm for deriving all such inequalities for the original causal structure that follow from ancestral independences in the inflation.
