[Shootout-list] Numerical medium-sized benchmarks

imo The short programs you provided are an excellent size-fit for the
Shootout. The heuristic I keep in mind is < ~100 lines of Java/C#

Providing a compiled language implementation, a JIT language
implementation, and an interpreted language implementation, gives us a
good enough idea of what the benchmark is like. You've provided enough
different implementations.

Hmmm, is there a MathWorld explanation for the mathematically
illiterate (like me)?

Where can we see a "math for dummies" explanation of the problem?

We're trying to keep to a smallish number of benchmarks - so for every
problem we add to the Shootout, we look for a problem to remove. Which
problems do you think could be replaced by the benchmarks you've
suggested?

Alternatively, what gap in Shootout benchmarks do these new problems
fill?

best wishes, Isaac
