long timeId = timeMillis / windowLengthInMs; return (int) (timeId % array.length()); }calculateTimeIdx 方法中,取余数就是实现循环利用数组。如果想要获取连续的一分钟的 Bucket 数据,就不能简单的从头开始遍历数组,而是指定一个开始时间和结束时间,从开始时间戳开始计算 Bucket 存放在数组中的下标,然后循...
Every time, after we calculate the answer to the corresponding range, we just maximize our calculated total answer. Let’s take a look at the solution to the described problem: algorithm maximumSumOverRangesSlidingWindow(A, n, k): // INPUT // A = array to calculate the answer for // n...
Sliding window algorithm is used to perform required operation on specific window size of given large buffer or array. 滑动窗口算法是在给定特定窗口大小的数组或字符串上执行要求的操作。 This technique shows how a nested for loop in few problems can be converted to single for loop and hence reduci...
Algorithm: For a given window, always keep the letter that appears the most and replace other letters. This minimizes replacement times. For a window of [i, j] with length L = j - i + 1, as long as L - maxFrequency <= k, we can keep extending this window's right bound by 1....

Sliding window median computation (algorithm-specific) The property of the aggregation algorithm defines the ability of the sliding window computation algorithm to be implemented in a runtime-efficient way. Moreover, the Median computation has some properties we need to consider: median depends only ...
VATE is also a parallel algorithm that can be deployed on GPU. With the parallel processing capability of GPU, VATE can estimate cardinalities of hosts in a 40 Gb/s high-speed network in real time at the time granularity of 1 s. In our experiments, VATE increases the state-preserving ...
a superclass of the star temporal graphs studied in Section 3) the running time of the algorithm is O(TΔ(n+m)⋅2Δ). In Section 5 we prove strong inapproximability results for SW-TVC, even in the special case where the length of the sliding window is Δ=2. In particular, we ...
