In this project, I made two interactive demonstrations of Simulated Annealing, using the javascript d3.js library.The first demonstration lets you use it to solve the classic physics brachistochrone problem:
However, the problem may actually be convex, so it doesn't demonstrate the true ability of SA.
For this, the second demonstration shows the physical situation where the name actually came from: relaxing a 2D grid of spins (the Ising Model) to its lowest energy state:
An accompanying article, going into much more detail, can be found on my blog here.
These are the main .py scripts that I use, in the main directory for simplicity. They are:
