Fine-tuning qSearchBreadth, qEpsilon, and nEpsilon. In particular I put
emphasis on choosing a move that is appealing as far as only the current block
is concerned. This is why nEpsilon is low (0.0001) and this is why qEpsilon is
higher (0.0004). The future possibilities that we consider are not as
important as is the placement of immediate block, in my opinion. This sort of
conundrum has been causing problems in the past.
