minimize(method=’Nelder-Mead’)

scipy.optimize.minimize(fun, x0, args=(), method='Nelder-Mead', tol=None, callback=None, options={'func': None, 'maxiter': None, 'maxfev': None, 'disp': False, 'return_all': False, 'initial_simplex': None, 'xatol': 0.0001, 'fatol': 0.0001, 'adaptive': False})

Minimization of scalar function of one or more variables using the Nelder-Mead algorithm.

Options

dispbool

Set to True to print convergence messages.

maxiter, maxfevint

Maximum allowed number of iterations and function evaluations. Will default to N*200, where N is the number of variables, if neither maxiter or maxfev is set. If both maxiter and maxfev are set, minimization will stop at the first reached.

initial_simplexarray_like of shape (N + 1, N)

Initial simplex. If given, overrides x0. initial_simplex[j,:] should contain the coordinates of the j-th vertex of the N+1 vertices in the simplex, where N is the dimension.

xatolfloat, optional

Absolute error in xopt between iterations that is acceptable for convergence.

fatolnumber, optional

Absolute error in func(xopt) between iterations that is acceptable for convergence.

adaptivebool, optional

Adapt algorithm parameters to dimensionality of problem. Useful for high-dimensional minimization [1].
