TRIANGLE_MONTE_CARLO is a C library which uses the Monte Carlo method to estimate the integral of a function F(X,Y) over the interior of the unit triangle in 2D.
The interior of the unit triangle in 2D is defined by the constraints:
0 <= X 0 <= Y X + Y <= 1The functions F(X,Y) are monomials, having the form
F(X,Y) = X^E(1) * Y^E(2)where the exponents are nonnegative integers.
