2026-04-01 A Dataset of Nonlinear Equations for Subdivision doi:10.57760/sciencedb.34211 en This dataset SDD is a collection of zero-dimensional square systems of nonlinear equations together with their solution information obtained mainly by subdivision methods. It contains 451 polynomial systems and 130 non-polynomial systems collected from the literature and public datasets, and 48000 nonlinear system instances generated from 5 families of parametric systems arising in practical applications. The solutions are obtained by two subdivision solvers IbexSolve and RealPaver as well as a symbolic solver RootFinding:-Isolate in Maple. More detailed information on the dataset can be found in the file readme.txt inside the main directory of SDD. This is the third version of SDD. In this verison, we have further fixed some errors in the second version for some systems. Please refer to revision-1.txt for the detailed difference between V1 and V2 and revision-2.txt for the the detailed difference between V2 and V3. subdivision; polynomial system; nonlinear equation; zero-dimensional system; non-polynomial system Juan Xu Huilong Lai Yingying Cheng Wenqiang Yang Changbo Chen PUBLIC https://creativecommons.org/licenses/by/4.0/ dataset Science Data Bank
