z | a temporal walk |
uv | the new directed edge that is being processed in the edge stream |
t(xy) | time of arrival of a multi-edge instance |
t _{ u} | last time an edge arrived leading to u |
β | decay exponent for the length of the walk |
γ | time-aware edge weighting function |
p(z,t) | weight of walk z at time t |
p(w,t) | sum of weight of walks ending in node w at time t |
p(xy) | sum of weight of walks ending with edge xy at time t(xy) |
