public void handleException(String experimentName,
 int iteration,
 Exception e,
 Optional<S> sOptional,
 I i,
 Algorithm<S,I> algorithm)

What should be done when there is an unhandled exception in the user algorithm implementation? Handle exception that is not controlled in the user code and reaches our executor. Behaviour can be customized or changed by extending the ExceptionHandler class.

Specified by:

handleException in class ExceptionHandler<S extends Solution<S,I>,I extends Instance>

Parameters:

experimentName - Experiment name

iteration - Iteration if known, -1 if not

e - Thrown exception

sOptional - Current solution, if available

i - Current instance

algorithm - Current algorithm

public String getStackTrace(Throwable t)

Generate stacktrace as string from throwable

Parameters:

t - Throwable

Returns:

Stacktrace as string
