“…The Gröbner basis method can be used to find all the minima of a polynomial function, as has recently seen some discussion in the literature [80,81]. A less well-known method is that of homotopy continuation [82,83], which has found use in several areas of physics [84][85][86], in particular finding string theory vacua [87,88] and extrema of extended Higgs sectors [89], where the authors investigated a system of two Higgs doublets with up to five singlet scalars in a general tree-level potential. In contrast, the Gröbner basis method is deemed prohibitively computationally expensive for systems involving more than five or six degrees of freedom [80], while for our purposes eight to ten degrees of freedom are necessary, and the solutions for thousands of parameter points needed to be calculated.…”
