Please note, it was Parisse asserting "comparison," not yangyongkang. The "confirmation" attempted, (by using Wolfram), was "also not ideal," which is the whole point. It's only a means of confirming results, not a competition event.

All of that is beside the point though, and no scapegoating is being presumed here. When we can discuss results, focused on facts, not personalities, so much the better. For example, I don't always use the Wolfram product when trying to reconcile results. It just happens to be under my fingertips at the keyboard, instead of loading another product, (like wxmaxima), and so forth.

The undertaking of XCAS, and Parisse' own background, and his relationship with hp over the years are sound credentials. It needs no defending. However, bugs, have been found, code has changed, and sometimes results were wrong.

These are to be expected, and there is no shame in confronting them, or defending the outcomes. Personal challenges don't serve the cause, and are pretty worthless, overall.
