simplex_monte_carlo, a FORTRAN90 code 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) <= 1
The functions F(X) are monomials, having the form
F(X) = product ( 1 <= I <= M ) X(I)^E(I)
where the exponents are nonnegative integers.
