Algorithm 846: MixedVol: a software package for mixed-volume computation
TL;DR: C++ MixedVol is a C++ software package that computes the mixed volume of n finite subsets of ℤn or the support of a system of polynomials in n variables to solve polynomial systems by the polyhedral homotopy continuation method.
Journal ArticleDOI
Mixed Volume Computation for Semi-Mixed Systems
Tangan Gao,Tien-Yien Li +1 more
TL;DR: Taking the special structure of the semi-mixed supports of the systems into account, the resulting algorithm can dramatically speed up the mixed volume computation, especially when the systems are unmixed, and improves the speed of the Li—Li algorithm by a considerable amount.
Journal ArticleDOI
Mixed volume computation via linear programming
Tangan Gao,Tien-Yien Li +1 more
TL;DR: In this article, a renewed algorithm is presented to calculate the mixed volume of the support of a polynomial system, where the key ingredient is a specially tailored application of LP feasibility tests.
Journal ArticleDOI
Balancing the lifting values to improve the numerical stability of polyhedral homotopy continuation methods
TL;DR: This work proposes a procedure that operates as an intermediate stage between the mixed-volume computation and the tracing of solution curves and computes new lifting values of the support of a polynomial system to produce better-balanced powers of the continuation parameter in the polyhedral homotopies.
