Subject: triangular array vs. walking the hash table

Author: Stuart Cracraft

In my search printout, for my per-iteration pv,
I print out the contents of pv[0][0] .. pv[0][pvlength[0]]
on the first line and then right under it I print out the
results of walking the hash table.

In most cases these agree. But fairly often, maybe one
iteration or two per search, the walk-the-hash-pv is
longer by a move or two than the triangular array pv.

So a few questions:

  1) my code blocks the backing up of the triangular array
     when the search has timed out. reasonable?

  2) is the above normal that walking the hash gives sometimes
     a longer pv?

  3) I update my triangular array in the main search and the
     quiescence search. reasonable?

  4) Anything else you can think of.

Thanks,

Stuart
