Parameters
_minimize_neldermead(func, x0, args=(), callback=None, maxiter=None, maxfev=None, disp=False, return_all=False, initial_simplex=None, xatol=0.0001, fatol=0.0001, adaptive=False, bounds=None, **unknown_options)

Parameters

disp : bool

Set to True to print convergence messages.

maxiter, maxfev : int

Maximum allowed number of iterations and function evaluations. Will default to N*200 , where N is the number of variables, if neither :None:None:`maxiter` or :None:None:`maxfev` is set. If both :None:None:`maxiter` and :None:None:`maxfev` are set, minimization will stop at the first reached.

return_all : bool, optional

Set to True to return a list of the best solution at each of the iterations.

initial_simplex : array_like of shape (N + 1, N)

Initial simplex. If given, overrides :None:None:`x0`. initial_simplex[j,:] should contain the coordinates of the jth vertex of the N+1 vertices in the simplex, where N is the dimension.

xatol : float, optional

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

fatol : number, optional

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

adaptive : bool, optional

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

bounds : sequence or `Bounds`, optional

Bounds on variables. There are two ways to specify the bounds:

  1. Instance of Bounds class.

  2. Sequence of (min, max) pairs for each element in x. None is used to specify no bound.

Note that this just clips all vertices in simplex based on the bounds.

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

Examples

See :

Local connectivity graph

Hover to see nodes names; edges to Self not shown, Caped at 50 nodes.

Using a canvas is more power efficient and can get hundred of nodes ; but does not allow hyperlinks; , arrows or text (beyond on hover)

SVG is more flexible but power hungry; and does not scale well to 50 + nodes.

All aboves nodes referred to, (or are referred from) current nodes; Edges from Self to other have been omitted (or all nodes would be connected to the central node "self" which is not useful). Nodes are colored by the library they belong to, and scaled with the number of references pointing them
