FindMinValue
FindMinValue[f, x]
gives the value at a local minimum of f.
FindMinValue[f, {x, x0}]
gives the value at a local minimum of f, found by a search starting from the point 
.
FindMinValue[f, {{x, x0}, {y, y0}, ...}]
gives the value at a local minimum of a function of several variables.
FindMinValue[{f, cons}, {{x, x0}, {y, y0}, ...}]
gives the value at a local minimum subject to the constraints cons.
FindMinValue[{f, cons}, {x, y, ...}]
starts from a point within the region defined by the constraints.
Details and Options
- FindMinValue[...] is effectively equivalent to First[FindMinimum[...]].
- If the starting point for a variable is given as a list, the values of the variable are taken to be lists with the same dimensions.
- cons can contain equations, inequalities or logical combinations of these.
- FindMinValue first localizes the values of all variables, then evaluates f with the variables being symbolic, and then repeatedly evaluates the result numerically.
- FindMinValue has attribute HoldAll, and effectively uses Block to localize variables.
- FindMinValue[f, {x, x0, x1}] searches for a local minimum in f using
and 
as the first two values of x, avoiding the use of derivatives. - FindMinValue[f, {x, x0, xmin, xmax}] searches for a local minimum, stopping the search if x ever gets outside the range
to 
. - Except when f and cons are both linear, the results found by FindMinValue may correspond only to local, but not global, minima.
- By default, all variables are assumed to be real.
- For linear f and cons, x
Integers can be used to specify that a variable can take on only integer values. - FindMinValue takes the same options as FindMinimum.
