But if it were just combining waves with a definite oscillation and adding them up, that would be a piece of cake for a computer to do.
If I set up waves with known amplitudes and synthesize them, I'll find that for essentially all random combinations of phases, the thing I get is an object not confined. It takes a very clever combination of the phases of all those waves to add up to something in only one region; and cancel out everywhere else.
People used to say that's an impossible problem. Then people got to thinking about the fact that there are going to be constraints coming from some rather mundane facts -- that in principle will make the problem of deducing the phase like the solution of a solvable puzzle.
