hi

Hi all

I'm from Montreal and I'm a CS/SE(*) researcher with interests in graph theory, NP-hard problems and combinatorial optimisation. During my Ph.D., a minor bug made me accidentally discover "something" that I, probably wrongly, call "number splitting".

Basically, given a number X and a sequence S of digits, can we split S into smaller parts so that the obtained numbers add up (or average) to X?

I don't think this is new territory for maths scholars but I could not find any existing references. May be this is simply not worthy of serious maths investigation. In any case, I made a game out of it: Mean Sumurai on Google Play for people interested [sorry for the plug]. My pseudonym Mean Maths is linked to the game and also my belief that some people out there like their maths to be "mean" and challenging. However, due to family pressure :-D, the game has different difficulty levels. So take a look whatever your actual maths skills ;-P

Best

Hi;

Welcome to the forum.


In mathematics, you don't understand things. You just get used to them.
I have the result, but I do not yet know how to get it.
All physicists, and a good many quite respectable mathematicians are contemptuous about proof.
