bounds (Set/Get) {ROI}

Bounds - Accessor and Mutator Functions

Description

The bounds of a given optimization problem (OP) can be accessed or mutated via the method 'bounds'.

Usage

bounds(x)

## S3 method for class 'OP'
bounds(x)

bounds(x) <- value

Arguments

x

an object of type 'OP' used to select the method.

value

an object derived from 'bound' ('V_bound') or NULL.

Value

the extracted bounds object on get and the altered 'OP' object on set.

Examples

## Not run: 
lp_obj <- L_objective(c(1, 2))
lp_con <- L_constraint(c(1, 1), dir="==", rhs=2)
lp_bound <- V_bound(ui=1:2, ub=c(3, 3))
lp <- OP(objective=lp_obj, constraints=lp_con, bounds=lp_bound, maximum=FALSE)
bounds(lp)
x <- ROI_solve(lp)
x$objval
x$solution
bounds(lp) <- V_bound(ui=1:2, ub=c(1, 1))
y <- ROI_solve(lp)
y$objval
y$solution
