Software tools for medium-scale systems of polynomial equations
Oh, sorry. I did not see that you worked with the actual problem (because I did not see that it was linked). I was wondering where you numbers came from... :) |

Software tools for medium-scale systems of polynomial equations
In this case it looks like it will use a general SQP approach, then. I somehow doubt that it will take only a few seconds to find a reasonable approximation to a global minimum of a long sum of squares in 12 variables, but I have not used Maple in a couple of years... |

slight extension to highlight difference between solving and SDP. |

Software tools for medium-scale systems of polynomial equations
What is Maple doing internally? For an arbitrary function, random search for a minimum is as good as any other method, so is it using random search? |

Variety of commutative semi group
@J.-E.Pin You are right, I have no idea what the difference between an identity and a relation may be in the context here. |

Variety of commutative semi group
Judging from the result that you expect, I'm suspecting that you are after the variety of a commutative semigroup ring? Maybe one that satisfies $x_i^2 = x_i^3$ for each indeterminate $x_i$? Please rework this questions, at the moment it makes no sense. |

I agree, and you explained it better than I did. |

Is an ideal generated by multilinear, irreducible, homogeneous polynomials of different degrees always radical?
