 Legendre-Gauss</a> quadrature.
 Because of its <em>non-adaptive</em> nature, this algorithm can
 converge to a wrong value for the integral (for example, if the
 function is significantly different from zero toward the ends of the
 integration interval).
 In particular, a change of variables aimed at estimating integrals
 over infinite intervals as proposed
