constraints:约束条件,可以是等式约束或不等式约束。 options:优化算法的可选参数,如迭代次数、收敛容差等。 Scipy Optimize minimize函数的应用场景包括但不限于: 优化问题:寻找函数的最小值或最大值。 参数拟合:通过最小化目标函数来拟合模型参数。 机器学习:在训练模型时,通过最小化损失函数来优化模型参数。

Interactively create and solve optimization problems with MATLAB, Optimization Toolbox, or Global Optimization Toolbox using a visual interface. Specify the objective and constraints, choose solvers, and set options.
If not given, chosen to be one of BFGS, L-BFGS-B, SLSQP, depending on whether or not the problem has constraints or bounds. args tuple Extra arguments passed to the objective function (func) and its derivatives (Jacobian, Hessian). options dict, optional Note that by default the ...
