While the mixed volume computation generates general interests of its own, its by-product the mixed cells are crucially important in solving polynomial systems numerically by the polynomial homotopy continuation methods. In 2005, a software package, MixedVol by T. Gao, T.Y. Li and M. Wu, emerged which led the existing codes for this purpose by a great margin. However, after MixedVol was published, T. Mizutani, A. Takeda and M. Kojima developed a more advanced algorithm based on dynamic evaluations of the mixed cells which leads MixedVol in speed by a substantial margin. Recently, we revised the method in MixedVol with different forms of dynamic evaluations implemented. The preliminary results show that the new MixedVol code overtakes the lead in speed once again.
