Evolutionary Simulations

Evolutionary Simulations, or agent auto-improvement, uses intelligent optimization algorithms to automatically discover the best configurations for your AI agents by testing variations of prompts, models, tools, and other hyperparameters. Instead of manual trial and error, let the system systematically explore and evolve your agent configurations to maximize performance while minimizing costs.

Why Use Evolutionary Simulations?

Finding optimal agent configurations is complex — with countless combinations of prompts, models, and parameters, manual optimization is time-consuming and often misses the best solutions. Evolutionary Simulations helps you:
  • Automatically discover optimal prompt variations
  • Find the best model-cost-performance balance
  • Optimize tool usage and agent workflows
  • Reduce operational costs while improving quality
  • Validate improvements with statistical rigor
  • Scale optimization across multiple parameters simultaneously

Use Cases

  • Prompt Engineering: Evolve prompts for better accuracy and relevance
  • Model Selection: Compare providers and versions systematically
  • Cost Optimization: Find configurations that reduce spending without sacrificing quality
  • Performance Tuning: Optimize for speed, accuracy, or specific metrics
  • A/B Testing at Scale: Test multiple variations simultaneously with statistical validation

How It Works

Evolutionary Algorithm

Evolutionary Simulations employs an intelligent optimization process:
  1. Baseline Establishment: Measures current performance metrics
  2. Hypothesis Generation: Creates improvement theories based on patterns
  3. Variation Creation: Generates promising configuration variations
  4. Parallel Testing: Runs multiple experiments simultaneously
  5. Statistical Analysis: Validates improvements with rigorous statistical tests
  6. Evolution: Best performers become parents for next generation
  7. Convergence: Stops when optimal configuration is found or criteria met

Optimization Strategies

The system uses multiple optimization strategies:
  • Grid Search: Systematic exploration of parameter space
  • Random Search: Stochastic sampling for unexpected discoveries
  • Bayesian Optimization: Intelligent selection based on prior results
  • Genetic Algorithms: Evolution through mutation and crossover
  • Multi-Armed Bandit: Balancing exploration vs exploitation

Creating an Evolutionary Simulation

Step 1: Access Auto-Improve

Navigate to your agent in the dashboard and click the “Auto-Improve” or “Evolutionary Simulations” tab. Here you can click into an existing run, or create a new improvement run with the ‘Create New’ button.

Step 2: Define Improvement Hypothesis

Start by articulating what you want to improve:
Improvement hypothesis input with generated plan

Writing Effective Hypotheses

Good Examples:
  • “Reduce response time by optimizing prompt length while maintaining accuracy”
  • “Improve customer satisfaction scores by refining tone and response structure”
  • “Minimize API costs by finding optimal model-prompt combinations”
Components of a Hypothesis:
  • Goal: What metric to optimize (accuracy, cost, speed)
  • Method: How to achieve it (prompt changes, model selection)
  • Constraint: What to maintain (quality thresholds, compliance)
The system automatically generates an improvement plan based on your hypothesis.

Step 3: Configure Hyperparameters

Add and select which parameters to optimize using the Parameter Blocks.

Available Hyperparameter Types

Prompts
  • Select multiple prompt versions to test
  • Create variations with different instructions
  • Test different formatting and structure
  • Combine prompts for multi-step workflows
Models
  • Compare different providers (OpenAI, Anthropic, etc.)
  • Test model versions (GPT-4, GPT-3.5, Claude)
  • Evaluate cost vs performance tradeoffs
  • Mix models for different tasks
Tool Calls
  • Enable/disable specific tools
  • Adjust tool parameters
  • Test tool combinations
  • Optimize tool usage patterns
Agents
  • Configure sub-agent workflows
  • Test different agent compositions
  • Optimize agent coordination
  • Evaluate standalone vs collaborative approaches
Custom Parameters
  • Define any JSON-configurable parameter
  • Test arbitrary configuration values
  • Create complex parameter spaces

Step 4: Select Datasets

Choose test datasets for consistent evaluation:

Dataset Configuration

Training Set (80%)
  • Used to evaluate configurations
  • Guides optimization direction
  • Provides performance metrics
Test Set (20%)
  • Validates final configuration
  • Prevents overfitting
  • Ensures generalization
Dataset Requirements:
  • Minimum 20 samples for statistical validity
  • Include edge cases and typical scenarios
  • Balance different input types
  • Define clear success criteria

Step 5: Set Statistical Parameters

Configure statistical rigor for results validation:
Statistical parameters configuration panel
P-Value Threshold
  • Default: 0.05 (95% confidence)
  • Lower values = higher confidence required
  • Affects when improvements are considered significant
Confidence Level
  • Default: 95%
  • Higher = more conservative optimization
  • Balances exploration vs exploitation
Train/Test Split
  • Default: 80/20
  • Adjust based on dataset size
  • Larger test sets = better validation

Step 6: Select Baseline:

After clicking ‘Run Configuration’, you can select a baseline for each paramter block:

Step 7: Define Stopping Criteria

After clicking ‘Run Configuration’ and Set when the optimization should stop:
Stopping criteria cards with various termination conditions
Available Criteria:
  • Cost Limit: Stop at spending threshold
  • Session Runs: Maximum test executions
  • Configurations Tested: Number of variations tried
  • Time Limit: Maximum optimization duration
  • Accuracy Threshold: Stop when target metric achieved
At least one criterion must be selected. The system stops when ANY criterion is met.

Step 7: Launch Optimization

Review configuration and start the evolutionary process.
