Dec 1, 2023 · This is a simple question from algorithms theory. The difference between them is that in one case you count number of nodes and in other number of edges on the shortest …

Jul 2, 2009 · I have a line from A to B and a circle positioned at C with the radius R. What is a good algorithm to use to check whether the line intersects the circle? And at what coordinate …

Robust peak detection algorithm (using z-scores) I came up with an algorithm that works very well for these types of datasets. It is based on the principle of dispersion: if a new datapoint is a …

1. Introduction In computer science, the time complexity of an algorithm quantifies the amount of time taken by an algorithm to run as a function of the length of the string representing the …

Apr 6, 2015 · I am looking for an explanation why the AStar / A* algorithm is called AStar. All similar (shortest path problem) algorithms are often named like its developer(s), so what is …

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 …

Jan 21, 2010 · I am learning algorithm analysis. I am having trouble understanding the difference between O, Ω, and Θ. The way they're defined is as follows: f(n) = O(g(n)) means c · g(n) is an …

Why am I getting "Invalid algorithm specified" exception Asked 14 years, 1 month ago Modified 4 months ago Viewed 46k times

Feb 22, 2010 · A common algorithm with O (log n) time complexity is Binary Search whose recursive relation is T (n/2) + O (1) i.e. at every subsequent level of the tree you divide …

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 …
