def feasibility_messages(action_name)
  action_name = action_name.to_sym
  feasible?(action_name) if @feasibility_messages&.[](action_name).nil? # If feasibility check hasn't been performed yet for this action, perform it now
  return @feasibility_messages[action_name]
end

#feasible?(action_name, recompute: false) ⇒ Boolean

Retrieves feasibility for the given instance Calling this with an invalid action name will always return true.

Returns:

  • (Boolean)
