This class represents a reduction that replaces symbolic parameters with
their constaint values.
     
    
    # S4 method for class 'EvalParams,Problem'
perform(object, problem)
# S4 method for class '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.
