Nothing short of wacky usage of plot() function with xspline to interpolate the points, but still a “parameter” short of Bezier’s curve. 🙂 Given two random vectors, you can generate a plot that, xspline will smooth out the plot and…

Little useless-useful R functions – Greedy Salesman
Travelling Salesman Problem is an NP-complete problem and an old mathematical problem. For this useless function, we will look for the nearest city from the previous city (or starting point) and repeat until we visit all cities. The greedy solution…

Kadane’s algorithm – finding maximum sum in contigous sub-array
The famous algorithm of contiguous subarray within a one-dimensional array of numbers that has the largest sum is called Kadane’s algorithm.
It looks for global maximum of positive sum on any sub-array, regardless of it’s starting position or it’s length. Numbers must be next or together in a sequence (without any number left out).
