Problem desciprtion: I have encountered the following issue when using the chisq CI test. If the number of nodes and/or the number of discrete classes is sufficiently large, then integer representations of numpy (int64) can overflow, resulting in an error. In particular, np.prod(cardSXY) at...

A simpler demonstration of this problem is calculating (½ × 2) mod 2. The naïve version gives you the correct 1 mod 2 = 1. The flawed incorrect version gives you (½ mod 2) (2 mod 2) mod 2 = (½ × 0) mod 2 = 0 mod 2 = 0. What’s going on? Is math broken?
Is the overhead of using an unordered_map that HIGH? Big enough to bring a x4 in time? Or am I missing something else? Thank you! EDIT Keeping memoization but using a 2D array instead of an unordered map did the trick.https://codeforces.com/contest/984/submission/276544726. Crazy. Than...

This is a rather lengthy question, previously asked onhttp://stackoverflow.com/questions/13382155/is-indexing-vectors-in-matlab-inefficient. Since I did not get any definitive answer, I decided to ask it here, where it is more likely that MATLAB engineers will look. ...
Sometimes, the situation is as if the compiler and the runtime are running on different processors. Years ago, I ran into the following problem. A program used 1D70 as a guard value, to represent infinity or "not yet set". Variables were set to this value using a ...

The problem gets worse when functions get a bit bigger, for example: pair<long long, long long> op_min(pair<long long, long long> p, pair<long long, long long> q): in 64-bit, a pair is stored in 2 registers for both arguments and the return value, so no extra stack is used;...
