A Not So Great New Simulation Scheme for the Heston Model

I recently saw a news about a great new simulation scheme for the Heston model by Abi Jaber .&#xA;The paper suggests it is better than the popular alternatives such as the QE scheme of Leif Andersen. Reading it quickly, perhaps too quickly, I had the impression it would be more accurate especially when the number of time-steps is small. &#xA; The scheme is simple to implement so I decided to spend…
