There is a one-dimensional cellular automaton consisting of cells. Cells are numbered from 0 to N − 1. Each cell has a state represented as a non-negative integer less than M. The states of cells evolve through discrete time steps. We denote the state of the i-th cell at time t as S( i, t).

Do you know "sed," a tool provided with Unix? Its most popular use is to substitute every occurrence of a string contained in the input string (actually each input line) with another string β. More precisely, it proceeds as follows. Within the input string, every non-overlapping (but possibly adjacent) occurrences of α are marked.
