Fractional powers not supported by ModelKit #498
Comments
It's true: fractional powers are not supported by Can you send a short example? Could it be an option to define a custom homotopy? See here: HomotopyContinuation.jl/src/model_kit/abstract_system_homotopy.jl Lines 87 to 103 in d40ec60

Could integration with Symbolics.jl, i.e., removal of the symengine dependency in favour of Symbolics.jl as suggested in #456, solve this issue? using Symbolics

No this is unfortunately not so straightforward. We internally have a fairly complex system for the evaluation of systems where the input are taylor polynomials. We need this for the predictor step to compute higher order derivatives of On the main branch we have already support for If somebody is interested in giving this a shot I can also provide more guidance. |
Fractional powers are sometimes desirable for parameters in parameter homotopy.
One can fix
