Generalized Pitch Detection

I'm not sure if I can capture my intuition about this, but let's try
anyway: There exists a class of problems which exhibit somewhat
periodic cost functions: let's call them Generalized Pitch Detection
problems (GPD). The problem with such problems is to add bias to the
estimator so it will go for the desired pitch, and not one of its

The grid estimation problem in Snowcrash is a GPD problem.
