英文摘要For computing only the isolated real solutions to a given polynomial system, a heuristic test is proposed to decide whether one homotopy path will converge to a real root, which is based on the asymptotic behavior of an angle defined by two points on the homotopy path. The data that the test requires is easily obtained from the points along the curve-following procedure in homotopy methods. The homotopy path-tracking may be sped up if we start the test before the endgames, since most divergent paths and paths heading to complex roots can be stopped tracking earlier and unnecessary endgames are avoided. Experiments show that the test works pretty well on tested examples. © 2018, Springer Nature Switzerland AG.
