We present here a summary of our work on 
/
discrimination.
In Sections 2 and 3 we discuss the
procedures used with the PISA and PISORP
codes to generate and analyze the data used for the simulations.
Section 4 discusses some of the details of the track and road-finding
procedures used in PISORP.
Section 5 summarizes results on the use of Discriminant Analysis.
In section 6 we discuss a technique that we have named
``Hit Pattern Recognition'' or ``Pattern Recognition'' which is
a simpler, more transparent technique than Discriminant
Analysis but which appears to be
equally powerful.
