This package provides several specialized routines for structured polynomial ideals. The sparsity structure of a polynomial set can be described with a graph. By exploiting some suitable "chordal completion" of this graph, it is possible to develop more efficient algorithms for several problems in computational algebraic geometry.
See installation and configuration for instructions on how to install this package.The examples below illustrate how to use this package to get the following properties of a structured ideal: compute elimination ideals, count the number of zeros, determine the dimension, decompose the variety.
