# ReasoningAgentRouter

!!! abstract "Overview"
    The ReasoningAgentRouter is a sophisticated agent routing system that enables dynamic selection and execution of different reasoning strategies based on the task requirements. It provides a flexible interface to work with multiple reasoning approaches including Reasoning Duo, Self-Consistency, IRE (Iterative Reflective Expansion), Reflexion, GKP (Generated Knowledge Prompting), and Agent Judge.

## Best Practices

!!! tip "Optimization Tips"
    1. **Swarm Type Selection**
        - Use ReasoningDuo for tasks requiring both analysis and action
        
        - Use SelfConsistency for tasks requiring high reliability
        
        - Use IRE for complex problem-solving requiring iterative refinement

    2. **Performance Optimization**
        - Adjust max_loops based on task complexity
        
        - Increase num_samples for higher reliability (3-7 for most tasks)
        
        - Choose appropriate model_name based on task requirements
        
        - Enable random_models_on for diverse reasoning approaches
        
        - Use eval mode for validation tasks with known answers

    3. **Output Handling**
        - Use appropriate output_type for your needs
        
        - Process batched results appropriately
        
        - Handle errors gracefully
        
    4. **Self-Consistency Specific**
        - Use 3-5 samples for most tasks, 7+ for critical decisions
        
        - Enable eval mode when you have expected answers for validation
        
        - Customize majority_voting_prompt for domain-specific aggregation
        
        - Consider random_models_on for diverse model perspectives
