Introduction
The goal of global tracking is to find and fit the tracks in a D0 event
using event data from one or more of the D0 subdetectors.
The input event data is a collection of clusters from each subdetector. The
output is a collection of global tracks where each track
contains a list of clusters and one or more kinematical fits based on this
list.
This page serves as the gateway for documentation of the D0 Run II global
tracking software. It describes (or provides links to)
the organization of the code and management and status of the project.

section.
Tracking algorithms:
Currenlty GTR group supports and develops four tracking algorithms:
road approach (default), histogramming method (HTF), elastic arms algrithms
and random search in SMT. More information is available
here.
