The algorithm was independently discovered as described in "Algorithms for Approximate String Matching", E. Ukkonen, `Information and Control' Vol. 64, 1985, pp. 100-118. Reading the papers then looking at the source code for an implementation should be …

Aug 26, 2008 · How do I calculate the distance between two points specified by latitude and longitude? For clarification, I'd like the distance in kilometers; the points use the WGS84 system and I'd like to unde...

Sep 1, 2009 · Algorithm A can't tell the difference between two similar inputs instances where only x 's value changes. If x is the minimum in one of these instances and not in the other, then A will fail to find the minimum on (at least) one of these two instances. In other words, finding the minimum in an array is in not in o(n) and is therefore in 𝛺(n).

Apr 26, 2017 · The brute force algorithm above is terribly inefficient and in addition to that generates multiple copies of the cycles. It is however the starting point of multiple practical algorithms which apply various enhancements in order to …

Dec 30, 2008 · A friend was in need of an algorithm that would let him loop through the elements of an NxM matrix (N and M are odd). I came up with a solution, but I wanted to see if my fellow SO'ers could come u...

Jan 8, 2011 · How would you go about testing all possible combinations of additions from a given set N of numbers so they add up to a given final number? A brief example: Set of numbers to add: N = {1,5,22,15,0...

Oct 23, 2012 · A* is just like Dijkstra, the only difference is that A* tries to look for a better path by using a heuristic function which gives priority to nodes that are supposed to be better than others while Dijkstra's just explore all possible paths. Its optimality depends on the heuristic function used, so yes it can return a non optimal result because of …

Sep 4, 2008 · I'm looking for a simple algorithm to generate a large number of random, aesthetically pleasing colors. So no crazy neon colors, colors reminiscent of feces, etc. I've found solutions to this pro...

Mar 22, 2019 · Could someone explain the difference between polynomial-time, non-polynomial-time, and exponential-time algorithms? For example, if an algorithm takes O(n^2) time, then which category is it in?

Feb 2, 2016 · 8 You could check Algorithm to compare two images in order to see the available methods for image comparison. Unless you want to recreate the full algorithms on your own, you should try to use already existing libraries or a least part …
