WebOverview¶. Sobol sequence generator (SSG) is one of the critical utilities needed by Monte-Carlo Simulation. The SSG utility can generate the sequence with a quasi-random distribution. The Sobol sequence is one of the most popular quasi-random sequence for its simplicity and efficiency in implementation. Specifically, sobol sequence in base b=2, it … WebSobol sequences. An independent LD bit-stream is generated by setting up the FSM using a different Sobol sequence. Note that this step is performed ofﬂine and the structure of the FSM will not change after implementation. Algorithm 1 demonstrates the procedure.
