1. 概述 在处理需要检查给定数组中某些范围的答案的问题时,滑动窗口算法可能是一种非常强大的技术。 在本教程中,我们将解释滑动窗口技术及其变体,即固定窗口大小和灵活窗口大小。此外,我们将提供两种变体的示例,以便更好地理解。 2. 理论思想 滑动窗口技术背后的主要思想是将两个嵌套循环转换为单个循环。通常,该技术...
fixed size sliding window和dynamic size sliding window fixed size sliding window: 当快指针增加的时候慢指针必须增加 non-fixed size sliding window: 快指针增加,慢指针不一定变化 使用滑动窗口可以线性时间解决问题而且可以减少空间消耗 Fixed Length Sliding Window: 1.Strstr: Return the index of the first oc...
Given an array nums, there is a sliding window of size k which is moving from the very left of the array to the very right. You can only see the k numbers in the window. Each time the sliding window moves right by one position. 这题要求找到given数组中任意定长的滑动窗口中数的最大值...

1. 创建SlidingWindowCounter(SlidingWindowCounter和SlotBasedCounter参考下面) counter = new SlidingWindowCounter(this.windowLengthInSeconds / this.windowUpdateFrequencyInSeconds); 如何定义slot数? 对于9 min的时间窗口, 每3 min emit一次数据, 那么就需要9/3=3个slot ...

This thesis describes a fully distributed approach to resource scheduling within a sliding time frame, implemented for a system of agents across multiple JADE platforms. All agents, with operations inside the current window, schedule tasks using recursive propagation and a sorting algorithm. Operations ...
