Sum of squares optimization built on top of picos. Easy access to pseudoexpectation operators for both formulating problems and extracting solutions via rounding algorithms.
Installation
To install from pypi:
pip install SumOfSquares
Examples
To compute the sum of squares decomposition of a polynomial: ```python
import sympy as sp x, y = sp.symbols('x y') p = 2x4 + 2x3*y - x2y2 + 5y4 prob = SOSProblem() c = prob.addsosconstraint(p, [x, y]) prob.solve() c.getsosdecomp() Matrix([ [5.0(-0.306x2 + y2)2], [2.057(0.486x2 + x*y)2], [ 1.047x*4]]) ```
