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 is Sliding Window Algorithm? Examples? - Stack Overflow
While solving a geometry problem, I came across an approach called Sliding Window Algorithm. Couldn't really find any study material/details on it. What is the algorithm about?

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 ...

What is the difference between an Algorithm and a Method
In CS, the algorithm is the steps and the method is the means by which we do an action. All the math formulas would be algorithms as they give us instructions how to find or do something--even if they are called methods in math. We would have to code methods in a program to implement actually implement them.

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 depend on the average density of points. The scales need to be int multiples of each other, such you build a grid you can use for efficient ...

algorithm - Difference and advantages between dijkstra & A star - Stack ...
A* is just like Dijkstra, the only difference is that A* tries to look for a better path by using a heuristic function which gives priority to nodes that are supposed to be better than others while Dijkstra's just explore all possible paths. Its optimality depends on the heuristic function used, so yes it can return a non optimal result because of this and at the same time better the heuristic ...

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 ...
