- The best shortest path algorithm - Stack Overflow
What is the difference between the "Floyd-Warshall algorithm" and "Dijkstra's Algorithm", and which is the best for finding the shortest path in a graph? I need to calculate the shortest path betw
- 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 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 - Programming theory: Solve a maze - Stack Overflow
0 The best way to solve a maze is to use a connectivity algorithm such as union-find which is a quasi-linear time algorithm assuming path compression is done Union-Find is a data structure that tells you whether two elements in a set are transitively connected
- Image comparison - fast algorithm - Stack Overflow
Each algorithm is best suited for certain types of image transformations and you can take advantage of that At the top, the fastest algorithms; at the bottom the slowest (though more accurate) You might skip the slow ones if a good match is found at the faster level file-hash based (md5,sha1,etc) for exact duplicates
- Minesweeper solving algorithm - Stack Overflow
Simple random guessing didn't produce good results I implemented this method into my solving algorithm in C++ by adding a linear system of equations-solver I am researching the difficulcy of Minesweeper by running tens of thousands games through the algorithm and doing statistics My algorithm solves upto 85% of (9,9,10) easy level minesweepers
- algorithm to sum up a list of numbers for all combinations
The best-known algorithm requires exponential time If there were a polynomial-time algorithm, then you would solve the subset sum problem, and thus the P=NP problem The algorithm here is to create bitvector of length that is equal to the cardinality of your set of numbers Fix an enumeration (n_i) of your set of numbers Then, enumerate over all possible values of the bitvector For each
- What algorithm gives suggestions in a spell checker? [closed]
What algorithm is typically used when implementing a spell checker that is accompanied with word suggestions? At first I thought it might make sense to check each new word typed (if not found in the dictionary) against it's Levenshtein distance from every other word in the dictionary and returning the top results
