About this pip-installable distribution package

This pip-installable source distribution sagemath-msolve provides an interface to msolve, which implements computer algebra algorithms for solving polynomial systems (with rational coefficients or coefficients in a prime field).

Examples

A quick way to try it out interactively:

$ pipx run --pip-args="--prefer-binary" --spec "passagemath-msolve[test]" ipython

In [1]: from sage.all__sagemath_msolve import *

In [2]: R = PolynomialRing(QQ, 2, names=['x', 'y'], order='lex')

In [3]: x, y = R.gens()

In [4]: I = Ideal([ x*y - 1, (x-2)**2 + (y-1)**2 - 1])

In [5]: I.variety(RBF, algorithm='msolve', proof=False)
Out[5]:
