This function estimates the integral using the Gaussian-Legendre quadrature method. It uses Legendre polynomial roots and weights to compute the integral over the given interval.

)Arguments
- period
Numeric vector, the integration interval, default is `c(0, 1)`.
- y_tilde
Numeric, parameter for the exponential function in the integrand.
- v_tilde
Numeric, parameter for the exponential function in the integrand.
- tau_tilde
Numeric, parameter for the exponential function in the integrand.
- n_points
Integer, the number of Gaussian points to use for the integration.
