- 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
- 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 - Peak signal detection in realtime timeseries data - Stack . . .
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 given x number of standard deviations away from a moving mean, the algorithm gives a signal The algorithm is very robust because it constructs a separate moving mean and deviation, such that previous
- What is the optimal algorithm for the game 2048? - Stack Overflow
AI Algorithm I found a simple yet surprisingly good playing algorithm: To determine the next move for a given board, the AI plays the game in memory using random moves until the game is over This is done several times while keeping track of the end game score Then the average end score per starting move is calculated
- Circle line-segment collision detection algorithm? - Stack Overflow
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 circles
- 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
- Tower of Hanoi: Recursive Algorithm - Stack Overflow
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 from Wikipedia: procedure
- 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
