In computer science, a disjoint-set data structure (also called a union–find data structure or merge–find set) is a data structure that tracks a set of elements partitioned into a number of disjoint (non-overlapping) subsets. It provides near-constant-time operations (bounded by the inverse Ackermann function) to add new sets, to merge existing sets, and to determine whether elements are ...

If "Path Compression" is enabled, finding a the representative for a set will result in all nodes along the find path being set as direct children of the representative. When unifying, this setting may cause "Union by Rank" to not work, since ranks are not changed as part of path compression.

    Union−Find Applications - Union−Find | Coursera

    We introduce the union−find data type and consider several implementations (quick find, quick union, weighted quick union, and weighted quick union with path compression). Finally, we apply the union−find data type to the percolation problem from physical chemistry. Percolation.java 1st edition. GitHub Gist: instantly share code, notes, and snippets.

Submit a .zip file containing only Submit only Percolation.java (using the weighted quick-union algorithm from WeightedQuickUnionUF) and PercolationStats.java. These should be very simple methods. Each of the methods (except the constructor) in Percolation must use a constant number of union-find operations. If you have a for loop inside of one of your Percolation methods, you're probably doing it wrong. Don't forget about the virtual-top / virtual-bottom trick described in lecture.

    PercolationStats.java: A class that prompts for N and T, performs T experiments on an NxN grid, and prints the mean, standard deviation, and confidence interval of the percolation threshold, and timings of percolation simulations. Though it is slightly inefficient, it's fine to use arrays or union-find objects that are slightly larger than strictly necessary. Doing this results in cleaner code at the cost of slightly greater memory usage. Each of the methods (except the constructor) in Percolation must use a constant number of union-find operations. The constructor should throw a java.lang.IllegalArgumentException if N 0. Performance requirements. The constructor should take time proportional to N2; all methods should take constant time plus a constant number of calls to the union- nd methods union(), find(), connected(), and count(). java P e r c o l a t i o n data / input10 . txt 56 open ...

    \$\begingroup\$ @I'lladdcommentstomorrow well, not exactly (my bad). There is an open(row, col) method that opens specified site at position row, col. Think of it like this: there is a fluid (blue boxes) that flows from top to bottom via open sites (starts from 0th row and can only flow through the open sites). As soon as fluid reaches the bottom site(s) we say that system percolates.
