I found the Numbo program interesting and much more plausible than the Jumbo program that Hofstadter talks about in the previous chapter. The reason I think that the Numbo program is more plausible is because unlike the Jumbo program, there is a relatively small set of ways that a particular problem can be solved. A human would figure out the solution in the simplest, most straight-forward way. There lies the task of the Numbo program: out of a list of solutions for a particular problem, which one is the simplest? While this is still a difficult problem to solve, it is not nearly as difficult as the Jumbo program where there are no clear solutions. Words are completely independent from each other, and there is no clear simplest way to solve Jumbo problems.
