遗传算法（Genetic Algorithm）是模拟达尔文生物进化论的自然选择和遗传学机理的生物进化过程的计算模型，是一种通过模拟自然进化过程搜索最优解的方法(Genetic Algorithm)

Maximum Length PN sequences are binary sequence generators that are capable of outputting all possible combinations of binary sequences in 2^m-1 cyclic shifts, where m is the size of the LFSR (Linear Feedback Shift Registers ) used in generating such sequences. Terms like Psuedorandom binary sequences (PRBS) or psuedonoise sequences are also used to refer m-sequences.
