#### Notes On Unbiased Random Walks

Imagine that a particle is walking in a two-dimensional space, starting at the origin . At every time-step (or “epoch”) it takes a vertical step. At every step, the particle either moves up by , or down by $altex -1$. 760 more words

#### Random Walks: Maths, Drunk Nights Out and Fighting Cancer

We’ve all had a few nights where we may have drunk a liiittle too much. I’m sure you can picture it now: stumbling around, head pounding, enjoying music that probably isn’t as good as you think it is… Well one angle on this behaviour that I am fairly sure you hadn’t previously considered is the fact that this kind of behaviour is of great mathematical interest. 651 more words

#### Random Walk and Brownian Motion, Discussion

Hi,

In article one of Brownian Motion Series I introduced the brownian motion and proved that it is the limit to a random walk. In article two I go back to the parent process of a brownian motion (random walk) and look at how properties of a random walk are maintained as we move from a random walk to a brownian motion. 62 more words

#### Markov Chain Monte Carlo: Simulated Annealing

# Markov Chain Monte Carlo: Simulated Annealing¶

In this post we will investigate a Markov chain Monte Carlo optimisation algorithm colloquially known as ‘Simulated annealing’. We will not outline any theory about Markov chains themselves in this post, we can save all that fun for another time. 3,476 more words
