scipy.optimize.minimize(function, data_x0, constraints=constarnt) This is how to input the constraints into the methodminimize().

constraints = [ {'type': 'ineq', 'fun': lambda x: 1 - (x[0] + x[1])}, {'type': 'ineq', 'fun': lambda x: x[0] - x[1]} ] ``` 然后,我们可以使用`minimize` 函数来求解优化问题: ```python result = minimize(lambda x: x[0]**2 + x[1]**2, x0=[0, 0], constra...
