# NArgMin

NArgMin[f, x]
gives a position at which f is numerically minimized.

NArgMin[f, {x, y, ...}]
gives a position at which f is numerically minimized.

NArgMin[{f, cons}, {x, y, ...}]
gives a position at which f is numerically minimized subject to the constraints cons.

## Details and OptionsDetails and Options

• NArgMin returns a list of the form .
• NArgMin[..., {x, y, ...}] is effectively equivalent to {x, y, ...}/.Last[NMinimize[..., {x, y, ...}, ...].
• cons can contain equations, inequalities, or logical combinations of these.
• NArgMin always attempts to find a global minimum of f subject to the constraints given.
• By default, all variables are assumed to be real.
• can be used to specify that a variable can take on only integer values.
• If f and cons are linear, NArgMin can always find global minima, over both real and integer values.
• Otherwise, NArgMin may sometimes find only a local minimum.
• If NArgMin determines that the constraints cannot be satisfied, it returns {Indeterminate, ...}.
• NArgMin takes the same options as NMinimize.
