In information filtering, the information vector and the information matrix are computed and propagated instead of the estimated state vector and the error covariance.
In a subsequent study, Wang et al. [143] show how the scanning technique, where MMS malware generate random phone numbers to which they try to propagate instead of using the address book of their host, increases the probability of a major outbreak, even when the market share of operating systems are too low for having a giant component.
However, an inverse effect in which sound wave energy propagates instead of attenuation will occur when both these two parameters are negative simultaneously.
In information filtering, the information vector and matrix are computed and propagated over time instead of the state vector and its error covariance.
In reality, the wave will propagate along the corridor (diffract at the corner point), instead of propagating through the three walls.
This modification is useful because, instead of propagating from a single query source node in the graph, we can propagate from several source nodes that all belong to the same family or superfamily that we are searching for.
Instead of propagating the approximate distance, [28] computes accurate distances of grid points to the initial interface, but propagates a reference to the surface patches to which the closest point projection refers to.
"What is important is to help Iran instead of propagating against Iran," he said.
So, instead of propagating N messages, each one saying "user U is now at location L", we can wait until there are N users at location L and only then propagate a single message saying "users U1..U N are now at location L" or (in case privacy is an issue) "N users are now at location L".
It is more accurate than the original Fast Marching Method because it computes the accurate distances to the boundary instead of propagating approximate values.
