- Complexity . The complexity of generated networks can be controlled in three ways: (1)

by specifying one of the three categories ('Low', manipulating the three columns with
single connections, 'Mid', manipulating the three columns with dual connections, and
'High', manipulating the column with triple connection), (2) by specifying any range of
consecutive columns between 1 and 7, and (3) by skipping a number of columns. A
number of equal column combinations can be created by all of these approaches, which is
an overlap to be eliminated after the programme testing stage is over.

- Maximum links at node . Has the same meaning as in the random generation.

4.7 TEST CASES

Three nodal sets have been used to test the tool: of 20, 77 and 200 junctions. The layout of
the first set has been already shown in Figure 4.16. The other two are shown in Figures 4.20
and 4.21, respectively.
