Hi,
is there any particular reason not to use a Set instead of a vector? It
solves the issue of distinct values. Or am I missing something?

Hi!
I have a sequence of natural numbers and I have to partition them into
more or less equals N groups.
Partitioning function is just a sum of numbers in a given group.
My naive solution is to sort numbers descending then take each number
and put into one of N groups in which sum of its

In the general case this is an NP-complete problem (ie, no algorithm
you can write will be good enough), but many simpler cases can be
solved quickly by some heuristic or other. See

examples.

Hi Warren,
Clojure doesn't try to be support every possible feature of Java when
generating Java classes, it just provides enough for interop purposes.
Annotations have always been a weak area. I don't know if annotations on
