Hi there and thanks for the note,

you unluckily found a bug not yet cleared in the online version. It
should help to replace line 215 in Processor.java:
---
resultPop = performPostProcessing();
---
by
---
resultPop = performPostProcessing();
if (resultPop==null) {
resultPop = goParams.getOptimizer().getAllSolutions().getSolutions();
}
---

I will hopefully consolidate an updated online version in the coming
week. And BTW, the mailing list is rather new and hasnt been very
active, so you didnt miss much. However I have no problem accessing the
archive... whats the error message you received?

Best wishes,
  Marcel Kronfeld
