SIMPLEX_MONTE_CARLO is a C++ library which uses the Monte Carlo method to estimate the integral of a function F(X) over the interior of the unit simplex in M dimensions.
The interior of the unit simplex in M dimensions is defined by the constraints:
0 <= X(1:M) sum ( 1 <= I <= M ) X(I) <= 1The functions F(X) are monomials, having the form
F(X) = product ( 1 <= I <= M ) X(I)^E(I)where the exponents are nonnegative integers.
