Heuristic-Based Verifiers
As an alternative to learned models, verifiers can be implemented using simpler, rule-based designs. These heuristic-based verifiers rely on straightforward methods to evaluate candidate solutions, rather than on complex patterns learned from data.

Final-Answer Verification
Automated Code Generation and Selection
A system is designed to solve complex math word problems. First, a language model generates five different step-by-step solutions for a given problem. Next, a separate component examines each of the five solutions, checks the final numerical answer for correctness against a known calculator result, and assigns a 'correctness score' to each. The solution with the highest score is then presented as the final answer. Which part of this system is acting as the verifier?

Majority Voting as a Verification Heuristic
A system is designed to answer simple factual questions. For any given question, it generates a list of five potential answers. The system must then choose the best final answer from this list. Which of the following methods for choosing the final answer relies on a simple, predefined rule rather than on complex patterns learned from a large dataset?
Choosing a Solution-Checking Method
A system designed to solve math problems generates multiple final answers. To select the best one, it uses a verifier that simply checks which answer is most frequently generated. This type of verifier is considered a complex, data-driven model because its selection is determined by the data (the generated answers).
