To check if a character is already in the substring, we can scan the substring, which leads to an O(n^2)O(n2) algorithm. But we can do better. By using HashSet as a sliding window, checking if a character in the current can be done in O(1). A sliding window is an abstract c...
12. What is the algorithm to use? 14 Patterns: 1. 🪟 Sliding Window : Longest Substring Without Repeating Characters Minimum Window Substring Longest Substring with At Most Two Distinct Characters Longest Substring with At Most K Distinct Characters Longest Repeating Character Replacement ...
a client could send 100 requests in the last second of the first minute and another 100 requests in the first second of the second minute, resulting in 200 accepted requests in 2 seconds. This library supports a flexible sliding window algorithm based on Redis backend which solves this problem...
We have presented in this paper a new algorithm, SW1PerS, for quantifying periodicity in time series data. The algorithm has been extensively tested and compared to other popular methods in the literature, using both synthetic and biological data. Specifically, with a vast synthetic data set span...
A relaxation of the sliding window model is the jumping window model [23], where the window does not advance continuously, but discretely in fractions of the measurement window. When operating under this model, we propose the following improvement over the Timestamp Vector algorithm that ...
Because the boundary is relatively stable, the cost of mining closed frequent itemsets over a sliding window is dramatically reduced to that of mining transactions that can possibly cause boundary movements in the CET. Our experiments show that our algorithm performs much better than representative ...

3 At the time that a new transaction is added to the sliding window, the window size is tem- porarily increased to N +1; after that, deleting a transaction from the sliding window will change the window size back to N . Therefore in our algorithm, we assume that the minimum support ...
Here, we demonstrate the utility of the sliding window algorithm as a robust and powerful deconvolution tool for comprehensive characterisation of charge variant analysis data for mAbs. Optimum performance is evaluated by studying the impact of critical software parameters on detection, identification and...
