一类二维可逆二阶元胞自动机中非零元胞的个数
On number of nonzero cells in some two-dimensional reversible second-order cellular automata
摘要：
本文证明了二维可逆二阶元胞自动机在第$n$步具有非零值的元胞个数的递推方程。初始配置是一个单元格，值为1，所有其他值为0。
英文摘要：
Recursive equations for the number of cells with nonzero values at $n$-th step for some two-dimensional reversible second-order cellular automata are proved in this work. Initial configuration is a single cell with the value one and all others zero.
