- Numerical methods: fast but unreliable.
- Qualitatively wrong results possible.
- E.g: missing or non-existing critical points.
- Symbolic methods: reliable but slow.
- Exponential in degree of polynomial.
- Up to degree 5 or so.
- Hybrid symbolic-numerical methods: reliable and faster.
- Still exponential complexity.
- Up to degree 10 or so.
Parallel processing to investigate high-degree curves/surfaces.
