This method is not implemented.

**gfan Documentation** This program is part of the Puiseux lifting algorithm implemented in Gfan and Singular. The Singular part of the implementation can be found in:Anders Nedergaard Jensen, Hannah Markwig, Thomas Markwig: tropical.lib. A SINGULAR 3.0 library for computations in tropical geometry, 2007 See alsohttp://www.mathematik.uni-kl.de/~keilen/de/tropical.htmland the paper Jensen, Markwig, Markwig: "An algorithm for lifting points in a tropical variety".Example:Run Singular from the directory where tropical.lib is located.Give the following sequence of commands to Singular:LIB "tropical.lib";ring R=0,(t,x,y,z),dp;ideal i=-y2t4+x2,yt3+xz+y;intvec w=1,-2,0,2;list L=tropicallifting(i,w,3);displaytropicallifting(L,"subst");This produces a Puiseux series solution to i with valuation (2,0,-2)Options:--noMult: Disable the multiplicity computation.-n value: Number of variables that should have negative weight.-c: Only output a list of vectors being the possible choices.

The object gfanTropicalLifting is a method function with options.
