SciPy - Advanced Optimization

Given the following code snippet, what will be printed during the optimization?

from scipy.optimize import minimize

def callback(xk):
    print(f"Step: {xk[0]:.2f}, {xk[1]:.2f}")

def func(x):
    return (x[0]-1)**2 + (x[1]-2)**2

res = minimize(func, [0, 0], callback=callback)

AMultiple lines showing parameter values approaching (1.00, 2.00)

BOnly one line showing initial parameters [0.00, 0.00]

CNo output because callback is ignored

DError because callback function has wrong signature

Step-by-Step Solution

Solution:

Step 1: Understand the callback usage in minimize
The callback prints the current parameters at each iteration during optimization.
Step 2: Analyze the expected output
Since the function minimizes distance to (1,2), parameters will update stepwise, printing multiple lines approaching (1.00, 2.00).
Final Answer:
Multiple lines showing parameter values approaching (1.00, 2.00) -> Option A
Quick Check:
Callback prints each step params [OK]

Quick Trick: Callback prints each iteration's parameters [OK]

Common Mistakes:

Assuming callback prints only once
Thinking callback is ignored by minimize
Believing callback signature is incorrect here
