1·Usually you want every instantiation of a distribution to represent an uncorrelated stochastic variable, which means that you should a new engine for each one.
通常你要分配的每个实例化代表着不相关的随机变量,这就意味着你应该为每一个新的引擎。
2·The convergence rate of deterministic signal is slower than the one of uncorrelated signal.
确定性信号的收敛速率慢于不相关信号的速率。
