# Imprecise nonlinear optimization [closed]

I want do do optimization to find the maximum of length of a vector under constraint of a polynomial in sagemath, but it output something strange. Is sagemath actually able to do such work?

```
#!/usr/bin/env sage
import sys
from sage.all import *
from scipy.optimize import NonlinearConstraint
# Assuming your vector is represented as a list or a vector in SageMath
x, y, z = var('x y z')
vector = [x, y, z]
# Define the optimization problem
initial_guess = [3, 3, 3]
def fun1(vector):
return -sum([v**2 for v in vector])
def fun2(x,y,z):
return x**2 + y**2 + z**2 -27
problemm = minimize(fun1, initial_guess, NonlinearConstraint(fun2,0,0))
print(problemm)
```

It gives output as below:

```
(600.1187424066786, 600.1187424066786, 600.1187424066786)
```
