Aiming at this point, it introduces the theory of Concurrent Branch Patterns, and puts forward Concurrent Branch Patterns Mining based on the Maximum forward Path and gives relevant arithmetic.

The discovery and use of the right algorithms, and clever implementations and application, are building blocks upon which the whole field takes collective steps forward.

A set of equations of optimal fixed-lag smoothing filter are obtained by using optimal fix-lag smooth time forward-recurrence algorithm and solving the built system mathematic model.
