tetrahedron01_monte_carlo

tetrahedron01_monte_carlo, a C++ code which uses the Monte Carlo method to estimate the integral of a function F(X,Y,Z) over the interior of the unit tetrahedron in 3D.

The interior of the unit tetrahedron in 3D is defined by the constraints:

        0 <= X
        0 <= Y
        0 <= Z
             X + Y + Z <= 1
      

        F(X,Y,Z) = X^E(1) * Y^E(2) * Z^E(3)
