- 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
- jwt - RS256 vs HS256: Whats the difference? - Stack Overflow
Both choices refer to what algorithm the identity provider uses to sign the JWT Signing is a cryptographic operation that generates a "signature" (part of the JWT) that the recipient of the token can validate to ensure that the token has not been tampered with RS256 (RSA Signature with SHA-256) is an asymmetric algorithm, and it uses a public private key pair: the identity provider has a
- 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
- What is the difference between a heuristic and an algorithm?
An algorithm is the description of an automated solution to a problem What the algorithm does is precisely defined The solution could or could not be the best possible one but you know from the start what kind of result you will get You implement the algorithm using some programming language to get (a part of) a program Now, some problems are hard and you may not be able to get an
- 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
- 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
- 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?
As opposed to repeated A* search, the D* Lite algorithm avoids replanning from scratch and incrementally repair path keeping its modifications local around robot pose if you would like to really understand the algorithm I suggest you start by reading through the pseudo code for A* and implement it
