Many advances have been made in recent years in the pricing of early exercisable derivatives using Monte Carlo simulation, but it is still a problem. The fundamental problem is that while existing techniques work, they generally require a degree of specialist handcrafting or sub-Monte Carlo simulations. The former requires an undesirable amount of research for new payouts and the latter results in models that are slower than is satisfactory.
