Search the Interval for Minimum and Maximum of the Function in R Programming – optimize() Function
optimize() or optimise() function in R Language is used to search the interval from lower to upper for a minimum or maximum of the function f with respect to its first argument.
Syntax: optimize(f, interval, maximum)
f: the function to be optimized. The function is either minimized or maximized over its first argument depending on the value of maximum.
interval: a vector containing the end-points of the interval to be searched for the minimum.
maximum: the logical value says to maximize or minimize. Its default value is minimize.
