Types - Accessor and Mutator Functions

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

types(x)

types(x) <- value

Arguments

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

Returns

a character vector.

Examples

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