"You can see these are not exactly small optimization problems. The smallest one has 89 parameters in the model, and the largest has 600."

Those are small optmization problems. These types of problems are solved in computer vision for hundreds of thousands of variables. His problem can be solved in real-time, not tens of seconds.

Compared to weather prediction, which is an optimisation problem involving hundreds of millions of variables, and occupies a hefty supercomputing cluster for a few hours.
