[GraphHopper] question on contraction

[Renaud De Landtsheer]

Hi Peter,

I was wondering if you could give me some hint with respect to the 
parameters of the contraction algorithm.

I'v identified the following parameters:
* periodicUpdates  The higher the values the longer the preparation 
takes but the less shortcuts are produced.
* lazyUpdates
* neighborUpdates

Can you hint me on the effect of the two last parameters on the speed of 
the contraction algorithm, and on the quality of the resulting contraction?

Thank you very much
