Subject [jira] [Commented] (SYNAPSE-1061) WeightedRRLCAlgorithm Unwanted condition

-----------------------------------------------------

Hi Vanji,

Shall we try to understand the logic behind reCalcuateWeight().

I am just wondering whether we have mistakenly put 

{code}
if (totalConnections > 0)
{code}

instead of 
{code}
if (totalConnections >= 0)
{code}

because totalConnections == 0 is explicitly handled within the method, which gives the idea
that we need to recalculate the weight for that case as well.

>  was going through with WeightedRRLCAlgorithm and noticed that useless condition used
in reCalcuateWeight(). Why do we need that condition over there and it is already known that
totalConnections is not a zero.
