gfanTropicalStartingCone(L)
gfanTropicalStartingCone(I)
This method compute a pair of Groebner bases as needed for gfanTropicalTraverse. It heuristically finds a cone of the Tropical Variety. Its first output is the Groebner basis of the cone's monomialfree initial ideal. And the second output is the Groebner basis of the original ideal. Note that gfanTropicalStartingCone uses graded reverse lex order.





gfan Documentation This program computes a starting pair of marked reduced Groebner bases to be used as input for gfan_tropicaltraverse. The input is a homogeneous ideal whose tropical variety is a pure ddimensional polyhedral complex.Options:g: Tell the program that the input is already a reduced Groebner basis.d: Output dimension information to standard error.stable: Find starting cone in the stable intersection or, equivalently, pretend that the coefficients are genereric.
The object gfanTropicalStartingCone is a method function with options.
