Locally "unshortable" paths in graphs
Setup: Consider a connected graph G, with diameter "d".
Informally: Trivially (by definition of diameter), taking any path $P$ any nodes $P(i) , P(i+k)$ for $k>d$ can be connected by a SHORTER path. …

What nodes of a graph should be vaccinated first?
Consider a graph, choose some "p: 0<p<1" (probability to infect the neighbor node).
Choose some random number "K" of nodes which are "infected" initially.
So we can generate epidemic model on a graph …
