1.1 maekawa 1: Mixed-volume computation and polyhedral continuation by static lifting in PHCv2.
2:
3: The algorithm used is based on the construction of a mixed subdivision,
4: based on Betke's formula for mixed volumes and the polyhedral homotopy
5: continuation methods developed by Huber and Sturmfels.
6:
7: This library features integer-valued and floating-point lifting functions.
8: The implementation of integer static lifting typically induces nested
9: subdivisions, with non-fine cells recursively refined by subdivisions.
10:
11: There are four parts in this library:
12:
13: 1. Integer-valued lifting, mixed subdivisions and polyhedral continuation
14: 2. Floating-point lifting, mixed subdivisions and polyhedral continuation
15: 3. Influence of points to mixed volume: a simple criterion
16: 4. Driver packages
