in OptimizerRunner.java:
public void run() {
try {
...SNIP...
scheduler.scheduleWithFixedDelay(...SNIP...);
long start = System.currentTimeMillis();
optimize();
long end = System.currentTimeMillis();
if (!cancelled) {
optimizerDialog.showProgress("Saving optimization results ...");
saveToFile();
long totalTimeInSecs = (end - start) / 1000;
showFastProgress(totalSteps, "Optimization");
MessageDialog.showMessage(...SNIP...);
}
} catch (Throwable t) {
Dispatcher.getReporter().report(t);
MessageDialog.showError(optimizerDialog, t.toString());
} finally {
scheduler.shutdownNow();
optimizerDialog.signalCompleted();
}
}
Maybe we should insert another "scheduler.shutdownNow();" after "optimize();"
otherwise "Saving optimization results ..." could be overrided with a "100 out
of 100 strategies proceed" ;)
