This class represents a reduction that replaces symbolic parameters with
their constaint values.

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

## Arguments

- object
A EvalParams 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 = EvalParams, problem = Problem)`

: Replace parameters with constant values.

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

: Returns a solution to the original problem given the inverse_data.
