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)
Parameters:
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.
Example 1:
Python3
f < - function(x) { 5 * x ^ 2 - 12 * x + 17 }
optimize(f, interval = c( - 5 , 5 ))
|
Output:
$minimum
[1] 1.2
$objective
[1] 9.8
Example 2:
Python3
f < - function(x) { 5 * x ^ 2 - 12 * x + 17 }
optimize(f, interval = c( - 5 , 5 ), maximum = T)
|
Output:
$maximum
[1] -4.999944
$objective
[1] 201.9965
