Schematic of dynamic string method. Multiple trajectories launched from the initial string images (blue circles) end at the black points. The averages of these end points determine the directions of the drift vectors (black arrows), and the new string images (purple circles) are moved in the direction of the drift vectors. This new string would then be reparameterized to achieve equal arc lengths between each pair of images along the string, where the total arc length of the string is free to change at each iteration.
