Example: make all the nodes
as blue as possible
We want to find the best solution to our spin glass problem. To begin try clicking on the most red nodes (which are bad, as indicated by the slider in the bottom left of the screen). In the first level, for example, try clicking on the top left node. The colour represents the "frustration" of each node. A highly frustrated (red) node corresponds to one that would reduce the total energy of the system if it is flipped.
Hint: If you get stuck just cick the nodes which are most red!
