In this post, we're going to continue looking at Richard Sutton's book, Reinforcement Learning: An Introduction. What we are doing here is generating future prices via a probability simulation of future outcomes. It includes a wide variety of force fields and MC techniques, and thus is applicable to a broad range of problems in molecular simulation. Monte Carlo simulation has traditionally been viewed as a very costly computational method, normally requiring very sophisticated, fast computer implementations in compiled languages. or we can use a Monte Carlo approach where we use the following algorithm: generate two uniform random deviates x and y over an interval [0,1] calculate the Cartesian distance r to the point they correspond to, r 2 = x 2 + y 2; test if r falls within the circle determined by the maximum radius of integration R; if r <= R, count this test as a "hit". You simply pass it the number of simulations you want to run, and a list describing each parameter, and it will return the Monte Carlo sample as a data frame. This chapter shows how to correctly discretize the square‐root diffusion in the CIR85 model and value zero‐coupon bonds numerically. Yes, it's inefficient for single integrals, but it's a great thing for students to look at because a) it's simple to understand (no need of calculus) and b) it's easy to code. montecarlo15 - testing multiple 50 50.
