Kdtree Nearest Neighbor

This method produces different results depending on what city is choosen as the starting point.This function determines the Nearest Neighbor routes for multiple starting points and returns the best of those routes. Platforms: Matlab

This implements a KDTree for nearest neighbor and range searching.The KDTree stores a N-dimensional set of points. The tree can be queried for all points within a Euclidian range in order O(sqrt(p)+k) time, where p is the number of points and k is the number of reported points. A nearest neighbor...

Requirements: - MATLAB 7.6 or higher Platforms: Windows, Mac, *nix, Matlab, BSD Solaris

This is just a brute force implementation of k nearest neighbor search without using any fancy data structure, such as kd-tree. However it is the fastest knn matlab implementation I can find.A partial sort mex function is implemented which is a simple wrapper of c++ partial_sort.Provided the sort... Platforms: Matlab

This is a small but efficient tool to perform K-nearest neighbor search, which has wide Science and Engineering applications, such as pattern recognition, data mining and signal processing.The code was initially implemented through vectorization. After discussions with John D'Errico, I realized... Platforms: Matlab

The 2-column vector contains cities' coordinates. The algorithm generates the optimal path to visit all the cities exactly once, and return to the starting city.The algorithm has its limitations, and based on the cities' distribution on the map it may or may not give the optimal solution.It...

I was playing the game Scramble on my iPod touch, and I realized that I wasn't very good. But the algorithmic challenge of writing a program to solve the Scramble (same as Boggle) game was too tasty to pass up. It was indeed quite challenging, but quite satisfying in the end. The program first... Platforms: Matlab
