    state: int
    action: int
    reward: float
    next_state: int
    ```

    #### 3. Implement Q-Learning and Policy
    ```python
    import torch

    class DeepPath:
    def __init__(self, num_states, num_actions, α, γ):
    self.Q = torch.zeros(num_states, num_actions)
    self= α
    self= γ

    async def q_learning_update(self, s, a, r, s_next):
    self.Q[s, a] += self* (r + self* torch.max(self.Q[s_next]) - self.Q[s, a])
    print(f"Q-learning update: s = {s}, a = {a}, r = {r}, s_next = {s_next}, Q = {self.Q}")

    async def policy(self, s):
    action_probs = torch.softmax(self.Q[s], dim=0)
    print(f"Policy: s = {s}, action_probs = {action_probs}")
    return action_probs

    async def train(self, environment, num_epochs):
    for epoch in range(num_epochs):
    print(f"Epoch {epoch+1}/{num_epochs}")
    s = environment.reset()
    done = False
    while not done:
    a = await self.policy(s)
    s_next, r, done = environment.step(a)
    await self.q_learning_update(s, a, r, s_next)
    s = s_next
    print(f"End of epoch {epoch+1}")

    async def execute_logic(self, state):
    action_probs = await self.policy(state)
    action = torch.argmax(action_probs).item()
    print(f"Logic execution: state = {state}, action = {action}")
    return action
    ```

    ### Practical Applications

    - **Recommendation Systems**: Enhances personalized recommendations by reasoning over knowledge graphs to understand user preferences and item relationships.
    - **Semantic Search**: Improves search engines by enabling them to understand and reason over semantic relationships between entities, providing more accurate search results.
    - **Healthcare**: Assists in medical knowledge discovery by reasoning over biomedical knowledge graphs to find connections between diseases, treatments, and genetic factors.

    These updated implementations include detailed logging at key steps in the execution process, providing verbose output that can be used as proof of the algorithms' operations.
