“…Transition matrix has been a useful tool for those special linear rules [2,7,[9][10][11][12]29,32,33], because for any 1D linear rule (or some 2D ones) with any given number of cells, there is a transition matrix whose reversibility is equivalent to that of the CA. However, this method has fundamental limitations since the matrix size is dependent on the number of cells: it is obviously unwise to calculate the determinant of the transition matrix for each cell number, instead, we hope to find an algorithm which can tell the relationship between the reversibility of the transition matrix and its size.…”
