A trick to reduce the space complexity is to notice that the recurrence relation doesn't need anything other than dpi+1dpi+1 when calculating dpidpi. Therefore, instead of creating a dpdp array, we can simply update the value of dpi+1dpi+1 using a variable. Here is how you might ...
In these cases, the DTW distance is represented by the LIS length of an integer sequence of length O(mn), or O(n2) when m=n. On the other hand, for some applications where c is a relatively large constant, the c2 overhead in the O(c2mn) complexity may become problematic. Thus, ...

We observe that in Lemma 2.1 the nτ-factor in the time complexity is due to matching X in the sampled suffix tree STi by passing the string τ times, each time with a different choice of j∈[1,τ], j≠i. Each such pass costs us O(nlognτ) time. The idea is to reduce th...
(DTW), respectively, it should be mentioned that some measures might improve in accuracy or execution time when combined with other time series distance functions or time series models. Examples include Bag-of-SFA-Symbols (BOSS) [28], complexity invariance distance (CID)time series shapelets [29...
We analyze the time complexity of Algorithm 4 and determine the main reasons for its poor efficiency. In Algorithm 4, the samples in the stream dataset S are inserted in QT, one by one. Suppose the number of sample points in the visible stream dataset Sv at the current time is n, and...
Is there a way to determine stored procedure complexity? Is there a way to insert the output of 'RESTORE HEADERONLY' or 'RESTORE FILELISTONLY' to a table? Is there a way to use a conditional where clause Is there a way to use aliases in a calculation? Is there a work-around to create...
[2] How do you manage the complexity of these seemingly-unwieldy pieces and translation layers? It seems like you have your own 'parser' implementation (maybe copied from the Go src tree? [3]). How will you keep your parser (as well as the rest of the system) up-to-date as Go ...
If the solution of the current graph is found to be time-infeasible and therefore additional nodes are required, they are added and the MILP formulation is adjusted. In contrast to branch-and-cut algorithms, in which constraints can be added during the exploration of the branch-and-bound tree...
Thus, the number of pebbles represents the amount of memory necessary to perform some set of computations. The natural complexity measures to optimize in this game is the minimum number of pebbles used, as well as the minimum amount of time it takes to finish pebbling all the nodes; these ...
