Paper studies non-tight reconstruction threshold in a 4-state model with different in/out block mutations.
problem Non-tight reconstruction threshold in a 4-state symmetric model with different in-block and out-block mutations.
method Inspired by the stochastic block model, rigorously analyzes conditions for non-tightness of the reconstruction threshold.
result Rigorously gives conditions for the non-tightness of the reconstruction threshold in a 4-state symmetric model.
