深度优先搜索(Depth First Search,简称DFS)与广度优先搜索(Breath First Search,简称BFS)是图论中两种非常重要的算法,也是进行更高的算法阶段学习的最后一道门槛。 搜索算法频繁出现在算法竞赛题中,尤其是深度优先搜索,在竞赛中,它是用来进行保底拿分的神器! 深度优先搜索属于图算法的一种。其过程是:对每一个可能的...

Let P be a palm tree generated by a depth-first search. Suppose the vertices of P are numbered in the order they are reached during the search (as is done by the procedure DFS above). We shall refer to vertices by their numbers. If u is an ancestor of v in the spanning tree T ...
For example, in the second position, the move preferred by the No tree model is losing and the one by the main model is drawn, but this relies on a specific 10-move forced sequence that can only be found through explicit search. B. Same as A., but lesioning the feature drop metric,...

First Contentful Paint (FCP)measures the time from the navigation or page-load to the point when the browser renders the first bit of content from the DOM (Document Object Model). This could be text, an image, or even a canvas render. It provides an idea of how long users wait to sta...
Depletion from suspension is a first-order process, analogous to dilution; the rate of the decline in the suspended population is described by an exponent (−rS), equivalent to −(ws/hm). Plainly, the greater is the particle-specific ws, the greater is the dependence upon a deep mixed...
The step size was 4 dB for the first four reversals and 2 dB thereafter. A run was completed after 12 reversals and the BT was taken as the arithmetic mean of the 20log(m) values at the last eight reversals. Data were acquired for four runs and the final BTs were calculated as the...
