What are quasi-random sequences and why do they help MC convergence?

• A. They reduce the number of simulations to one.
• B. Quasi-random or low-discrepancy sequences (Sobol, Halton) fill space more evenly than pseudorandom draws, improving convergence.
• C. They replace MC with a single deterministic path.
• D. They are unrelated to convergence.

Answer: (B)
