The only difference with Dimer Cooing 4 is the timescale. In Dimer Cooling 4 (as in the previous ones), each frame corresponds to a certain number of performed flips (namely 16 for Dimer Cooling 4). Here, Each frame corresponds to a certain number of randomly chosen vertices (around which a flip is not always possible or performed!), namely 2000 here.
