The Table 2 demonstrates the potential of CAM as an associative memory
model. Column II of Table 2 depicts the maximum number of patterns that an
n -cell GMACA can memorize. The results of Hopfield Net on the same data set
are provided in Column III for the sake of comparison. The experimental result
clearly indicates that :
(i) the memorizing capacity of GMACA is found to be more than
20% of its lattice size ; and
(ii) it is superior to conventional Hopfield Net by 33% .
4.2 Evolution Time
The Table 3 represents the evolution time to evolve GMACA by Simulated An-
nealing . Column I and II of Table 3 represent different CA size ( n ) and number of
attractors ( k ) respectively; while the Column III depicts the Initial Temperature
required to find out the best possible GMACA configuration by SA .In Column
IV , we provide the evolution time required to synthesize GMACA . Growth of
time, as the results indicate, is super linear in nature.
