Two more cents : - we do not focus Alt-Ergo in particular when designing our way of generating VCs, but rather what can be handled by simplification inside Qed ; - my personal experience on comparing CVC4 and Alt-Ergo is that the former is stronger at lemma instantiation, and the latter is stronger in arithmetics ; but it is just a feedback on a very specific project.
