BARKERNEL

Newton barrier: Defines how centrality is weighted in the barrier algorithm.

Double

>=+1.0	Increases the emphasis on centrality when larger value is set.
<=-1.0	Selects a value adaptively in every iteration from [+1, -BARKERNEL].

0.0

Increasing this parameter may increase the number of iterations, therefore the recommended range is [1,2] and [-2,-1].
