Class BootStepper

x.__init__(...) initializes x; see help(type(x)) for signature

Parameters:

• maxArchSize - How many position vectors can be stored. This is normally used to (loosely) enforce a memory limitation for large jobs.
• parallelSizeDiv - For use when there are several cooperating MCMC processes that share data. When >1, this allows each process to have smaller stored lists. Normally, parallelSizeDiv is between 1 and the number of cooperating processes.
• lop - These are a list of starting postions that should be evaluated first and used as the basis for further exploration.
• v - A covariance matrix for non-bootstrap steps. Mostly, the system takes bootstrap steps that are adaptively derived from previous steps. However, to generate the list of previous steps, it needs a way to generate steps ab initio. So, v is used to get things going. v is also used occasionally thereafter, just to make sure the stepper doesn't get trapped in some subspace.

In subclasses, this takes a step and returns 0 or 1, depending on whether the step was accepted or not.
