- How does a diff algorithm work, e. g. in VCDIFF and DiffMerge?
Here is a page that includes a bit of documentation, full source code, and examples of a diff algorithm using the techniques in the aforementioned algorithm The source code appears to follow the basic algorithm closely and is easy to read There's also a bit on preparing the input, which you may find useful
- algorithm - Calculate distance between two latitude-longitude points . . .
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
- What are some algorithms for comparing how similar two strings are?
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 minimum number of single-character edits required to change one word into the other Strings do not have to be the same length Hamming Distance : The number of characters that are different in two equal length
- algorithm - Most efficient way to calculate Levenshtein distance . . .
The wikipedia entry on Levenshtein distance has useful suggestions for optimizing the computation -- the most applicable one in your case is that if you can put a bound k on the maximum distance of interest (anything beyond that might as well be infinity!) you can reduce the computation to O(n times k) instead of O(n squared) (basically by giving up as soon as the minimum possible distance
- algorithm - Finding all possible combinations of numbers to reach a . . .
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
- Where can I find information on the D* or D* Lite pathfinding algorithm?
To help others understand D* Lite more intuitively, I've created a Unity-based visualization tool that walks through the algorithm using step-by-step snapshots It's designed to clearly show how the algorithm responds to changes in the environment, which is a key feature of D* Lite
- algorithm - How to find convex hull in a 3 dimensional space - Stack . . .
The algorithm find the successive convex hull vertex like this: the vertex immediately following a point p is the point that appears to be furthest to the right to someone standing at p and looking at the other points
- algorithm - Difference between Big-O and Little-O Notation - Stack Overflow
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)
