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?

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 …

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 …

Aug 3, 2009 · Although I have no problem whatsoever understanding recursion, I can't seem to wrap my head around the recursive solution to the Tower of Hanoi problem. Here is the code …

What you're looking for are called String Metric algorithms. There a significant number of them, many with similar characteristics. Among the more popular: Levenshtein Distance : The …

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 …

At each iteration the algorithm chooses a node to expand from the open set (the one with the lowest f function - the f function is the sum of the cost the algorithm already knows it takes to …

The answer may still be interesting for somebody else: One may apply a variation of the marching square algorithm, applied (1) within the concave hull, and (2) then on (e.g. 3) different scales …

Jan 22, 2017 · I came up with this algorithm for matrix multiplication. I read somewhere that matrix multiplication has a time complexity of o(n^2). But I think my this algorithm will give o(n^3). I …
