, where ξ is the position of the pseudoparticle, and CV is current position on the reaction coordinate. To ensure that the reaction coordinate is almost equal to the coordinate of the pseudoparticle, a high value for the coupling constant k is typically chosen. The pseudoparticle is propagating on the potential g(ξ) + Q(ξ, CV ), where g(ξ) is the biasing potential. The biasing potential g(ξ)
