Subject: Why recalculation from scratch?

Hello there,

I noticed that in "The New Routing Algorithm for the ARPANET" [John M.
McQuillan], lots of work had been done on how to avoid recalculation from
scratch in link state routing. Why OSPF does recalculate from scratch? Does
it mean that CPU cost is negligible?

Many thanks.
