The Sequential Task

Now that results have been written to the result file, the meta model can be build.

spot("java0.conf","seq")

The sequential call generates a new design file (DES), which is shown here.

In order to improve confidence, the best solution found so far is evaluated again. To enable fair comparisons, new configurations are evaluated as many times as the best configuration found so far. Note, other update schemes are possible.

If SPOT's budget is not exhausted, the new configurations are evaluated, i.e., run is called again, which updates the result file. In the following step, seq is called again etc.

To support exploratory data analysis, SPOT also generates a best file. The content of the BST file after the run is finished is shown here.

The best file is updated after each SPOT iteration and can be used for an on-line visualization tool, e.g., to illustrate search progress or stagnation. The variable COUNT reports the number of REPEATS used for this specific configuration.
