Apparently posts containing only upper-case words are changed to lower case (other than each word's first letter), but upper-case words in mixed-case posts keep their case.
I have not been having much luck with any approach at the moment.
I am looking for a way to represent the whole thing with one multivariate gf.
That is a good question. The problem leads to 20 diophantine equations. Every diophantine equation of the linear type can be represented by a gf. Now they have to be solved in relation to each other to get the number of solutions for the entire system.
What are simultaneous gfs?
Yep, 20 of them for that problem!
It is a type of problem that occurs frequently and I have never really solved one, a simultaneous gf!!!!!
Sure looks like it.
It is lucky that you have not. It is a dilly.
Oh, that one. Well, I haven't worked on it much.
It is sort of a combination of sudoku and a rubiks cube.
I do not remember working on a sudoku problem...
It might not be the same problem but I worked on a projecteuler problem. I think it was #300? It should have me on the solution list.
I do not remember your solution.
