For two trajectories N and M, the time complexity of the DTW algorithm can be presented as O(N M).Assuming that N > M , the time complexity is determined by the highest time spent to find the distance between the two trajectories, so in this case, time complexity of the algorithm will be O(N²).. DTW algorithm is known to have …

Time Warp Edit Distance (TWED) is a measure of similarity (or dissimilarity) for discrete time series matching with time 'elasticity'. In comparison to other distance measures, (e.g. DTW (dynamic time warping) or LCS (longest common subsequence problem)), TWED is a metric. Its computational time complexity is , but can be drastically reduced in some specific situations by using a corridor to reduce the search space. Its memory space complexity can be reduced to .
