Minima

This script implements data structures for solving the following two problems: - Range minimization: given an array X of data, quickly find min(X[i:j]) for different ranges i:j. - Least common ancestors: given a tree, quickly find the lowest tree node that is an ancestor of all of a given set...

An animated simulation of Particles in 2D searching for a global minima of a simple function using Particle Swarm Optimization algorithm

This script provides the final interval of uncertainty in which the minima of single variable non linear/linear function. The function should be unimodal in the interval. The script checks the unimodality of the function.User inputs the initial interval and the number of iterations. depending...


Platforms: Matlab

unimodality of a single variable function in a given interval refers to existence of at the most only one maxima or minima. This script checks the unimodality of the function in the interval provided by the user.

This function quickly finds local peaks or valleys (local extrema) in a noisy vector using a user defined magnitude threshold to determine if each peak is significantly larger (or smaller) than the data around it. The problem with the strictly derivative based peak finding algorithms is that if...

This is a very simple function to find the local maximum in any dimensional array. As simple as it is it still gives nice results.I use the imdilate() function as a maximum operation and then compare the data to the result.The function receives three parameters:the data, a vector defining the...


Platforms: Matlab

Let r_scale be the neighborhood radius scale, a brute search method would require N*r_scale to detect the valleys with neighborhood size of r_scale in 1d signal or N*r_scale*r_scale complexity in 2d image. Which is too slow in large data size. In this file, the complexity is reduced in...

While working with a histogram we may need to detect a peak or crest of the histogram.But the histogram contains a number of local minima & maxima which makes the histogram extremely uneven.While detecting a peak or crest we are intended to detect the global peak or crest.This code replaces every...

This is a large set of test functions, which may be used to test the effectiveness of global optimization algorithms. Some are rather easy to optimize (rosenbruck, leon, ...), others next to impossible (crosslegtable, bukin6, ...).All the test-functions are taken from either [1], [2] or [3] (see...
