Why do the following three characters have not symmetric toLower, toUpper results /** * Written in the Scala programming language, typed into the Scala REPL.
Given a set of 2D points, I want to calculate a measure of how horizontally symmetrical and vertically symmetrical those points are.
If there is a symmetry relationship in a table, how to represent it in开发者_运维问答 a elegant way?
I have an algorithmic problem in which I have derived a transfer matrix between a lot of states. The next step is to exponentiate it, but it is very large, so I need to do some reductions on it. Speci
This may be more appropriate for math overflow, but nevertheless: Given a 3D structure (for example, a molecule), what is a good approach/algorithm to find symmetry (rotational/reflection/inversion/e
the answer to this question is probably \"not possible\", but let me ask regardless :) Assuming we have a very simple JAVA class that has a primary key, for example:
