Image computation is the key step in fixpoint computations that are extensively used in model checking. Two techniques have been used for this step: one based on conjunction of the terms of the transition relation, and the other based on recursive case splitting. We discuss when one technique outperforms the other, and consequently formulate a hybrid approach to image computation. Experimental results show that the hybrid algorithm is much more robust than the "pure" algorithms and outperforms
more &raquo; ... oth of them in most cases. Our findings also shed light on the remark of several researchers that splitting is especially effective in approximate reachability analysis.
