Subject: Follow the same path until another is significantly better
X-Git-Url: http://git.tdb.fi/?a=commitdiff_plain;h=cac4176a9685e8b39147d1e18d969b3bee052b03;hp=cac4176a9685e8b39147d1e18d969b3bee052b03;p=r2c2.git

Follow the same path until another is significantly better

This replaces the cost penalty for routing steps.  In the penalty approach
it was possible to get two or more steps with the same penalty, which
would then race with each other.  In the new approach, all other steps are
sorted by their unpenalized cost and only the preferred one gets special
treatment.
