As for subspace based MUD, two improved algorithms are shown from the point of view of subspace tracking to solve the problems of slow tracking and unstable performance in traditional methods.

The agent that updates the index database with new documents is currently rather slow and is not optimized, which can be fixed by adding a couple of tracking fields to the index documents.

Ina long tracking shot at the start of the film, a feral cat prowls thiswasteland until it is felled by a slow-motion arrow.
