example_experiment2 module documentation

A short and simple example experiment with restarts.

The script is fully functional but also emphasises on readability. It features restarts, timings and recording termination conditions.

To benchmark a different solver, fmin must be re-assigned and another elif block added around line 119 to account for the solver-specific call.

When calling the script, previously assigned variables can be re-assigned via a name=value argument without white spaces, where value is interpreted as a single python literal. Additionally, batch is recognized as argument defining the current_batch number and the number of batches, like batch=2/8 runs batch 2 of 8.

Examples, preceeded by "python" in an OS shell and by "run" in an IPython shell:

example_experiment2.py budget_multiplier=3  # times dimension

example_experiment2.py budget_multiplier=1e4 cocopp=None  # omit post-processing

example_experiment2.py budget_multiplier=1e4 suite_name=bbob-biobj

example_experiment2.py budget_multiplier=1000 batch=1/16

Post-processing with cocopp is only invoked in the single-batch case.

Details: batch=9/8 is equivalent to batch=1/8. The first number is taken modulo to the second.
