Randomly Generate Points in a Spiral Motion using Javascript
So I have a javascript program that currently gets random points, it generates a random x,y,z value around the center point, within the radius r
How to do scalar multiplication and matrix inverse when variables are of size 1000 bits?
I am doing arithmetic operations on really huge numbers.
Turning n-dim points into m-dim where m<n and where point-to-point distance deviation is minimized
I want to apply k-means clustering to a (sparse) adjacency graph. For this I need to assign the nodes to a position in an euclidean space. Trivially I can do this by having a space with as many dimensions as there are nodes where each component corresponds to another node.
Interview puzzle on traveling on a line segment
On a number line of length M, where 0 < M <= 1,000,000,000, you given N (1 < N <= 100,000) integer pairs of points. In each pair, the first point represents where an object is currently located, and the second point represents where an object should be moved. (Keep in mind the second point may be smaller than the first).
Algorithm to detect a CLICK within Square range
It might be a simple question but I am looking for optimal solution. I will have numbers printed on a screen and I will be aware of coordinates. Numbers/Symbols will have 4 points(Square) to define their boundaries. Coordinates of that particular symbol will be stored in a file. Lets’ say there is a number 5 and it’s 4 coordinates on screens are:(2,20,20,20,2,40,20,40)
Randomness of wrapped RNG
There are plenty of questions around regarding random number generation, but I couldn’t find anything that exactly matched my question. Apologies if I missed one.
I’m trying to create a visual representation of something, but I don’t know what words to use, so I’ll try to describe it
My project team is making a site that will use reddit style voting to track users’ opinions on various issues, and use the data to create a “heat map”. I say heat map in quotes because I’m not sure that it’s the correct term – I don’t have the math to express it properly.

strategies for dealing with machine epsilon
Say you have a situation where you divide and then multiply a float, and you need to guarantee that it survives macheps (ie multiplication output equals division input). What are known strategies for guaranteeing this? Rounding would work, but anything else?
what is a efficient way to find repeating decimal
I am trying to find a efficient algorithm in Java to find the repeating decimal part of two integers a and b where a/b.
