  junction tree
Our algorithm departs from a direct adaptation of probabilistic propagation algorithms since it avoids the transformation of the initial network into a junction tree which is known to be a hard problem.
      
Principles of local computation are outlined for the graphical models, and an algorithm for implementing such computation over the junction tree is described.
      
Adding an extra local domain can lower the junction tree complexity.
      
A junction tree is a tree, in which each node is a clique from the original graph.
      
A junction tree is a structure that efficiently divides the original problem into subproblems.

  join tree
This allows propagation to be done exactly using the Shenoy-Shafer architecture for computing marginals, with no restrictions on the construction of a join tree.
      
At other times three or four of them, like strands in a cable, join tree and tree and branch and branch together.
      
Bayesian propagation also sometimes requires that we embed clusters of variables in a join tree.
      
Comparing these two algorithms is problematic since the join tree algorithm is not query based.
      
In dimension four and 4 The names join tree and split tree refer to the convention of sweeping from lower to higher values.

  connection tree
The new architecture employs the Mobile Virtual Circuit (MVC), a dynamic connection tree in which routes are predetermined but not set up for potential handoff connections.
      
The connection tree reconfigures after each handoff to enable continuous support of successive handoffs.
      
The connection tree can be freely defined by the user in order to construct novel algorithms starting from existing solvers.
      


Future mobile communication networks will be based on asynchronous transfer mode(ATM) and support various multimedia services. To acquire seamless fast handoffs in such an environment, we propose a fast handoff management scheme which uses permanent virtual connections(PVC) as backup between neighboring base stations. We calculate the handoff blocking probability for the given PVC bandwidth. The proposed scheme results in significant saving of wired link resourses, compared with Acampora's approach.In addition,...
