The Report Task

If SPOT's termination criterion is fulfilled, a report is generated. By default, SPOT provides as simple report function which reads data from the RES file and produces the following output:

 Best solution found with 507 evaluations:
Y          SIGMANULL VARA VARG COUNT CONFIG
0.1029542  0.445661 1.050709   72     5    110

The best solution found by SPOT has an average function value $Y= 0.1029542$. The automatic tuning process found an initial stepwidth SIGMANULL = 0.445661, the value VARA = 1.050709 for the stepsize multiplier, and the history length VARG = 72 . The average function value $Y= 0.1029542$ is based on five (COUNT = 5) algorithm runs. This configuration is the 110th configuration used in the SPOT run.

The output from Fig. 3 is shown by default after the tuning process is finished.

The user can choose alternative report functions or even add new report functions to SPOT.
