- Basic validation
- consists in the application of Newton's method
on the list of solutions. There are facilities to extract the
generating solutions when the symmetry group is submitted.
- Winding numbers
- can be computed by homotopy continuation
methods. The user must provide a start system with solutions at t < 1.
- Polyhedral validation
- is based on the output file of poco,
where the polyhedral end game was turned on. This validation
puts up a frequency table of computed path directions.
