### Disjoint Set UnionCompetitive Programming Algorithms

Disjoint Set Union. This article discusses the data structure Disjoint Set Union or DSU . Often it is also called Union Find because of its two main operations. This data structure provides the following capabilities. We are given several elements each of which is a separate set. A DSU will have an operation to combine any two sets and it

VisuAlgo was conceptualised in 2011 by Dr Steven Halim as a tool to help his students better understand data structures and algorithms by allowing them to learn the basics on their own and at their own pace. Together with his students from the National University of Singapore a series of visualisations were developed and consolidated from simple sorting algorithms to complex graph data

Motivation. The reason why Pigo has been developed is because almost all of the currently existing solutions for face detection in the Go ecosystem are purely bindings to some C/C libraries like OpenCV or dlib but calling a C program trough cgo introduces huge latencies and implies a significant trade-off in terms of performance. Also in many cases installing OpenCV on various platforms is

Nov 18 2019 · The tree contains a total of 31 nodes where the leaf nodes or the elements of original array starts from node 16. So we can easily construct a segment tree for this array using a 2 N sized array where N is number of elements in original array. The leaf nodes will start from index N in this array and will go upto index (2 N1).

Sep 23 2019 · Total time 224 ms ± 11.4 ms per loop (mean ± std. dev. of 7 runs 1 loop each) Count for k-d-tree 687 369. From the timings we can see that it took some 40 ms to construct the tree however the querying step only takes in the range of 100 µs which is therefore even faster than the numba-optimized boolean indexing.

Then T1 − f e is a tree and it has the same weight as T1 since T1 has minimum weight and the weight of f cannot be less than the weight of e otherwise the algorithm would have chosen f instead of e. So T1 − f e is a minimum spanning tree containing E1 e and again P holds.

Aug 31 2019 · Prim s algorithm is a greedy algorithm. It finds a minimum spanning tree for a weighted undirected graph. This means it finds a subset of the edges that forms a tree that includes every vertex where the total weight of all the edges in the tree is minimized. The algorithm operates by building this tree one vertex at a time from an arbitrary
