While solving a geometry problem, I came across an approach called Sliding Window Algorithm. Couldn't really find any study material/details on it. What is the algorithm about?

Jul 30, 2012 · The algorithm is ray-casting to the right. Each iteration of the loop, the test point is checked against one of the polygon's edges. The first line of the if-test succeeds if the point's y-coord …

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 path between …

Feb 16, 2010 · I'm looking for a very simple algorithm for computing the polygon intersection/clipping. That is, given polygons P, Q, I wish to find polygon T which is contained in P and in Q, and I wish T …

The algorithm picks on a number A along the curve, then looks up the safe distance and jumps to the next hashtable, or at least the algorithm does those factor checks until the next hashtable becomes …

Apr 29, 2012 · O (n) means that the algorithm's maximum running time is proportional to the input size. basically, O (something) is an upper bound on the algorithm's number of instructions (atomic ones). …

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 problem into half and do …

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 along the …

Mar 5, 2012 · Average case = arithmetic mean. Run the algorithm many times, using many different inputs of size n that come from some distribution that generates these inputs (in the simplest case, …
