constraints function

Constraints - Accessor and Mutator Functions

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

constraints(x)

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

constraints(x) <- value

Arguments

• x: an object used to select the method.
• value: an R object.

Returns

the extracted constraints object.

Examples

## minimize: x + 2 y
## subject to: x + y >= 1
## x, y >= 0
x <- OP(1:2)
constraints(x) <- L_constraint(c(1, 1), ">=", 1)
constraints(x)
