Programming Assignment 1: Percolation
Write a program to estimate the value of the percolation threshold via Monte Carlo simulation.
public class Percolation { public Percolation(int N) // create N-by-N grid, with all sites blocked public void open(int i, int j) // open site (row i, column j) if it is not open already public boolean isOpen(int i, int j) // is site (row i, column j) open? public boolean isFull(int i, int j) // is site (row i, column j) full? public boolean percolates() // does the system percolate? }
public class PercolationStats { public PercolationStats(int N, int T) // perform T independent experiments on an N-by-N grid public double mean() // sample mean of percolation threshold public double stddev() // sample standard deviation of percolation threshold public double confidenceLow() // low endpoint of 95% confidence interval public double confidenceHigh() // high endpoint of 95% confidence interval }
Example values after creating PercolationStats(200, 100) mean() = 0.5929934999999997 stddev() = 0.00876990421552567 confidenceLow() = 0.5912745987737567 confidenceHigh() = 0.5947124012262428 Example values after creating PercolationStats(200, 100) mean() = 0.592877 stddev() = 0.009990523717073799 confidenceLow() = 0.5909188573514536 confidenceHigh() = 0.5948351426485464 Example values after creating PercolationStats(2, 100000) mean() = 0.6669475 stddev() = 0.11775205263262094 confidenceLow() = 0.666217665216461 confidenceHigh() = 0.6676773347835391

Testing correctness of Percolation *----- Running 15 total tests. Tests 1 through 8 create a Percolation object using your code, then repeatedly open sites by calling open(). After each call to open(), we check the return values of isOpen(i, j) for every (i, j), the return value of percolates(), and the return value of isFull(i, j) for every (i ...

CS200 - Programming Assignment 2: Percolation Motivation Percolation refers to the movement of a uid through a porous material, but there are many systems that are mathematically similar, and percolation theory is the study of the general principles behind percolation. The following are examples of percolation: water owing through ground co ee ...
Percolation. We model the system as an n -by- n grid of sites. Each site is either blocked or open; open sites are initially empty. A full site is an open site that can be connected to an open site in the top row via a chain of neighboring (left, right, up, down) open sites. If there is a full site in the bottom row, then we say that the system ...

As suggested here I created my own percolation file starting from a solved nonogram . I have designed the bitmap image in Photoshop and created a class that converts the black and white BMP image to the TXT file format as accepted by the PercolationVisualizer provided as a testing tool for this assignment. Files can be found in /Percolation/src ...
Percolation - 110 course points. The purpose of this assignment is to practice your understanding of the Union-Find data type and the 2D array data structure. Start your assignment early! You need time to understand the assignment and to answer the many questions that will arise as you read the description and the code provided.
PercolationVisualizer.java animates the results of opening sites in a percolation system specified by a file, performing the following steps: Read the grid size n from the file. Create an n -by- n grid of sites (initially all blocked). Read in a sequence of sites (row, col) to open from the file. After each site is opened, draw full sites in ...

The fraction of sites that are opened when the system percolates provides an estimate of the percolation threshold. \n Performance requirements. \nThe constructor should take time proportional to n2; all methods should take constant time plus a constant number of calls to the union-find methods union(), find(), connected(), and count().
