It is difficult to make a direct and meaningful comparison like this. Without a container, the reaction system has less parameters, and thus the sampled parameter space is smaller. The aim in the paper, was to simply show that encapsulating a Schlogl model which was bistable in bulk condition, seemed to destroy this bistability.
The authors write (case 1): “of the 5000 parameter set tested under constant surface area, 82% (4098) gave a single fixed point, 321 15.7% (785) gave two fixed points, and 2.3% (117) no fixed points.” How this statistics compare with a similar one, performed on a similar chemical situation without container? Could the authors add the results of the same within a not confined environment?
