WebMar 4, 2024 · Brownian bridges is just a means of producing a Brownian path W, and Monte Carlo is a means by which we can evaluate expectations and integrals. Regular Monte Carlo would use a pseudo-random point set U to estimate such things, whereas quasi-Monte Carlo would use a low-discrepancy point set U ~.

WebBrownian bridges are placed over the different sections of the trajectory, and these functions are then summed over the area. The brownian bridge approach therefore smoothes a trajectory.
