In science:

For finite N , sn is reduced due to the presence of loops in the network, which causes the emergence of attrition of the paths.
Self-avoiding walks on scale-free networks
However, the self-avoiding property causes attrition of the paths, in the sense that a large fraction of paths generated in a stochastic manner have to be abandoned because they are overlapping.
Self-avoiding walks on scale-free networks
Here we study long-range properties of SAWs on equilibrium scale-free networks, and discuss the ‘attrition problem’.
Self-avoiding walks on scale-free networks
IV we analyze the length at which non-reversal random walks intersect themselves in these networks (self-intersection length), and in Sec. V we calculate the average attrition length of kinetic growth SAWs, at which they cannot continue without violating the self-avoidance condition.
Self-avoiding walks on scale-free networks
These walks were studied to describe the irreversible growth of linear polymers , and will allow us to consider the ‘attrition length’ for a walk on a given network (see Sec. V).
