You can prove that, at any timet[x]is accessed, then all ancestors ofx(excludingx) have lazy value pushed. 2D segment tree Assumes the array size isn*m. Ifn*mfits in memory, then it's possible to make the segment tree array(2*n)*(2*m)and turn the for loop into two of them ...

segment treeRecently, the Graphics Processing Unit (GPU) has been used to deploy high-speed software routers. On this platform, designing an efficient IP lookup engine is still a challenging task, especially when taking into account the comprehensive performance under frequent updates. Existing ...
For n-vertex graphs with treewidth $$k = O(n^{1/2-\epsilon })$$ and an arbitrary $$\epsilon >0$$ , we present a word-RAM algorithm to compute vertex
Lastly, its ability to compute both link- and node-disjoint trees makes it a versatile solution for diverse scenarios. 3. Multiple disjoint tree algorithm This section introduces MDTA, an algorithm focused on the fast computation of multiple fully link- or node-disjoint trees. Firstly, this ...
Image segmentation is the process of separating pixels of an image into multiple classes, enabling the analysis of objects in the image. Multilevel thresholding (MTH) is a method used to perform this task, and the problem is to obtain an optimal threshol
Taken together, Scarf represents a comprehensive toolkit for the analysis and integration of even the largest single-cell datasets on desktop computers, making single-cell genomics available to a significantly larger segment of the research community while simultaneously and significantly driving down the ...
Fifth, iSeg is relatively easy to use with few parameters to be tuned by the users. Here we describe the method in detail, followed by per- formance analysis using multiple data types including sim- ulated, benchmark, and our own. The data types include DNA copy number variations (CNVs)...
(2*u, ll, (ll+rr)/2and2*u+1, (ll+rr)/2+1, rr: they appear four times. They will be reduced efficienly in new style. 2. New style Forcing people to use a personal style is a bad idea. I share with you this style to give you a suggestion in coding segment tree. ...
