## Detailed Description

### template<class RNG = PseudoRandom, class S = Statistics>
class QuantLib::MCBarrierEngine< RNG, S >

Pricing engine for barrier options using Monte Carlo simulation.

Uses the Brownian-bridge correction for the barrier found in Going to Extremes: Correcting Simulation Bias in Exotic Option Valuation - D.R. Beaglehole, P.H. Dybvig and G. Zhou Financial Analysts Journal; Jan/Feb 1997; 53, 1. pg. 62-68 and Simulating path-dependent options: A new approach - M. El Babsiri and G. Noel Journal of Derivatives; Winter 1998; 6, 2; pg. 65-83

Tests:
  the correctness of the returned value is tested by reproducing results available in literature.
