Maximum - Accessor and Mutator Functions

Description

The maximum of a given optimization problem (OP) can be accessed or mutated via the method 'maximum'. If 'maximum' is set to TRUE the OP is maximized, if 'maximum' is set to FALSE the OP is minimized.

Usage

maximum(x)

maximum(x) <- value

Arguments

`x`	an object used to select the method.
`value`	an R object.

Value

a logical giving the direction.

Examples

## maximize: x + y
## subject to: x + y <= 2
## x, y >= 0
x <- OP(objective = c(1, 1), 
        constraints = L_constraint(L = c(1, 1), dir = "<=", rhs = 2),
        maximum = FALSE)
maximum(x) <- TRUE
maximum(x)
