Two of the most important areas in computational finance: Greeks and, respectively, calibration, are based on efficient and accurate computation of a large number of sensitivities. This paper gives an overview of adjoint and automatic differentiation (AD), also known as algorithmic...

Several exchanges in futures and options deploy pro-rata matching. The executed size of limit orders in pro-rata markets is never certain, unlike in price-time priority matching systems. This article derives the optimal size of limit orders in pro-rata markets given the trader's desired...

In this paper, we evaluate American-style, path-dependent derivatives with an artificial intelligence technique. Specifically we use swarm intelligence to find the optimal exercise boundary for an American-style derivative. Swarm intelligence is particularly efficient (computation and accuracy)...

We propose a simple risk-adjusted linear approximation to solve a large class of dynamic models with time-varying and … non-Gaussian risk. Our approach generalizes lognormal affine approximations commonly used in the macro-finance literature … risk-adjusted linearizations. We provide a formal foundation for approximation methods that remained so far heuristic, and …
