The 2-adic complexity and the 1-error 2-adic complexity of single cycle T-functions [PDF]
, 2014 The 2-adic complexities of the coordinate sequences derived from single cycle T-functions over F 2n were investigated.Let j be an integer such that 0≤ j≤n−1.It is shown that the 2-adic complexity of the j th coordinate sequence is upper bounded by lb(22j+

Zhejiang Daxue xuebao. Lixue ban, 2015 在逻辑函数布尔c-导数的基础上，引入了布尔c-偏导数的概念.为了简化布尔c-导数及其c-偏导数的计算，提出了基于逻辑函数最小项表的计算方法.该算法用最小项表列出1值最小项的二进制代码，然后对二进制代码中相应位取反变换产生新的最小项，再进行比较并删除新最小项中的重复项来计算c-导数和c-偏导数.实例展示了利用最小项表的计算过程.与代数法和图形法相比，该算法简单有效，当变量数较多时易于计算机编程实现.
