I am currently studying as an MSCS student and my research is based on Evolutionary Algorithm as Reinforcement Learning, and I am confused about the following terms:

1. What is the difference between Evolutionary Reinforcement Learning and Evolutionary Algorithm by considering it as Reinforcement Learning?
2. if the Evolutionary Algorithm is Reinforcement Learning, what's the definition of state?
3. which part of the Evolutionary Algorithm is the rewards of Reinforcement Learning?
4. What will be the transition and Action function? can anyone please help me with this
