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

and 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.
```
