c - How is a CRC32 checksum calculated? - Stack Overflow
Your code is a bit hard to understand, partly because it's incomplete: temp and testcrc are not declared, so it's unclear what's being indexed, and how much data is running through the algorithm. The way …
What is the difference between a heuristic and an algorithm?
Feb 25, 2010 · 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 …
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 …
Is there an efficient algorithm to generate a 2D concave hull?
The answer may still be interesting for somebody else: One may apply a variation of the marching square algorithm, applied (1) within the concave hull, and (2) then on (e.g. 3) different scales that my …
