Abstract: In this paper, we present a new partial order reduction algorithm that can help reduce both space and time requirements of on-the-fly explicit enumeration based verifiers. The partial order reduction algorithms described in [God95, HP94, Pel94, Pel96] were observed to yield very little savings in many practical examples. The reason was traced to the proviso in these algorithms that often caused their search to generate many unnecessary states. Our algorithm, called the two-phase algorithm,... (Update)
