- 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
- 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
- What algorithm can be used for packing rectangles of different sizes . . .
Huang has an algorithm that separates the problem of finding the smallest enclosing bounding box from the problem of deciding whether or not a set of rectangle can fit in a bounding box of a specific size You give his program a set of rectangles, and it tells you the smallest enclosing bounding box required to pack them
- 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
- Best algorithm for efficient collision detection between objects
It would be great if the algorithm also supported visibility query too, for the rendering pipeline For the sake of simplicity, assume that collision detection here is broad-phase (i e all dynamic objects are just perfect spheres)
- algorithm - What does O (log n) mean exactly? - Stack Overflow
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 constant amount of additional work
