Module for random array distribution

[Tomek]

Hello!

First of all, it is very hard to search CPAN for that module, cause almost
all modules contain words array and distribution

What am I going to achieve is to semi-randomly fill an array. There are 2
main goals: sum of elements, and min/max for each elem)

I have for example 2000 to split between 100 array elements. I don't want
to do this equally ( 100 x 20 ), but want to set a deviation, for example
50% so that minimum value for element is 5 and maximum is 15. All that
have to sum up to 2000 at the end.

I am sure somebody already written such module, I just can find it

Regards, T. Kraus

The word "array" is not going to be particularly useful, anyway. Most
modules are going to be named by what they do, not by what data structure
they will use to store the results of what they do.

That isn't unambiguously described. How do you get the 5 and 15 out of
50%? What distribution must the numbers approximately follow (uniform,
gaussian, exponential, don't care)? Do the min and max and the sum need to
be achieved precisely or only asymptomatically?

I don't see why this would be particularly likely to have had a module
written for it. It seems like a pretty unusual request, at least as
stated.
