I don't have a picture of general anolog programming, but a concrete example is devising a strategy to hit some balls in a game of pool. Like in a neural net, this can take the form of turning a few knobs until you get the right result. The reasons it can require less energy includes error tolerance, as mentioned in the article. The foundation of digital computer is error correction, so this trade-off could be the fundamental difference between the two.
