We study the complexity of the decision problem consisting in to decide whether an arbitrary site initially in state 0 will change to state 1. We show that the problem in the class $\mathbf{NC}$ proving a characterization of the maximal sets of stable sites as the tri-connected components. %G English %Z TC 1 %Z WG 1.5 %2 https://inria.hal.science/hal-01656355/document %2 https://inria.hal.science/hal-01656355/file/447449_1_En_9_Chapter.pdf %L hal-01656355 %U https://inria.hal.science/hal-01656355 %~ INSERM %~ IRD %~ CEA %~ BRGM %~ CNRS %~ UNIV-ORLEANS %~ IRSTEA %~ INRA %~ IFIP-LNCS %~ IFIP %~ IFIP-TC %~ IFIP-TC1 %~ IFIP-WG1-5 %~ IFIP-AUTOMATA %~ AGREENIUM %~ IFIP-LNCS-10248 %~ INSA-GROUPE %~ INSA-CVL %~ INRAE
