This class represents a reduction that flips a minimization objective to a
maximization and vice versa.

```
# S4 method for FlipObjective,Problem
perform(object, problem)
# S4 method for FlipObjective,Solution,list
invert(object, solution, inverse_data)
```

## Arguments

- object
A FlipObjective object.

- problem
A Problem object.

- solution
A Solution to a problem that generated the inverse data.

- inverse_data
The inverse data returned by an invocation to apply.

## Methods (by generic)

`perform(object = FlipObjective, problem = Problem)`

: Flip a minimization objective to a maximization and vice versa.

`invert(object = FlipObjective, solution = Solution, inverse_data = list)`

: Map the solution of the flipped problem to that of the original.
