27.3.1 Comparison with Knowledge-Based Scheme

The purpose of this chapter is to evaluate the quality of the configuration which is
autonomously determined by our scheme for different initial conditions.
Two experiments were conducted using the parameters described in Table 27.2. In
the first, we manually created a good initial configuration assuming a priori knowl-
edge of system parameters. We then ran the application and verified that the final
configuration did not substantially depart from the initial one. We consider a good
