# Protocol 10 v2.0 Implementation Summary
|
||||
|
||||
**Date**: November 20, 2025
|
||||
**Version**: 2.0 - Adaptive Two-Study Architecture
|
||||
**Status**: ✅ Complete and Ready for Testing
|
||||
|
||||
## What Was Implemented
|
||||
|
||||
### 1. Adaptive Characterization Module
|
||||
|
||||
**File**: [`optimization_engine/adaptive_characterization.py`](../optimization_engine/adaptive_characterization.py)
|
||||
|
||||
**Purpose**: Intelligently determines when enough landscape exploration has been done during the characterization phase.
|
||||
|
||||
**Key Features**:
|
||||
- Progressive landscape analysis (every 5 trials starting at trial 10)
|
||||
- Metric convergence detection (smoothness, multimodality, noise stability)
|
||||
- Complexity-aware sample adequacy (simple problems need fewer trials)
|
||||
- Parameter space coverage assessment
|
||||
- Confidence scoring (weighted combination of all factors)
|
||||
|
||||
**Adaptive Behavior**:
|
||||
```python
|
||||
# Simple problem (smooth, unimodal):
|
||||
required_samples = 10 + dimensionality
|
||||
# Stops at ~10-15 trials
|
||||
|
||||
# Complex problem (multimodal with N modes):
|
||||
required_samples = 10 + 5 * n_modes + 2 * dimensionality
|
||||
# Continues to ~20-30 trials
|
||||
```
|
||||
|
||||
**Confidence Calculation**:
|
||||
```python
|
||||
confidence = (
|
||||
0.40 * metric_stability_score + # Are metrics converging?
|
||||
0.30 * parameter_coverage_score + # Explored enough space?
|
||||
0.20 * sample_adequacy_score + # Enough samples for complexity?
|
||||
0.10 * landscape_clarity_score # Clear classification?
|
||||
)
|
||||
```
|
||||
|
||||
**Stopping Criteria**:
|
||||
- **Minimum trials**: 10 (always gather baseline data)
|
||||
- **Maximum trials**: 30 (prevent over-characterization)
|
||||
- **Confidence threshold**: 85% (high confidence required)
|
||||
- **Check interval**: Every 5 trials
|
||||
|
||||
### 2. Updated Intelligent Optimizer
|
||||
|
||||
**File**: [`optimization_engine/intelligent_optimizer.py`](../optimization_engine/intelligent_optimizer.py)
|
||||
|
||||
**Changes**:
|
||||
- Integrated `CharacterizationStoppingCriterion` into the optimization workflow
|
||||
- Replaced fixed characterization trials with adaptive loop
|
||||
- Added characterization summary reporting
|
||||
|
||||
**New Workflow**:
|
||||
```python
|
||||
# Stage 1: Adaptive Characterization
|
||||
stopping_criterion = CharacterizationStoppingCriterion(...)
|
||||
|
||||
while not stopping_criterion.should_stop(study):
|
||||
study.optimize(objective, n_trials=check_interval) # Run batch
|
||||
landscape = analyzer.analyze(study) # Analyze
|
||||
stopping_criterion.update(landscape, n_trials) # Update confidence
|
||||
|
||||
# Stage 2: Strategy Selection (based on final landscape)
|
||||
strategy = selector.recommend_strategy(landscape)
|
||||
|
||||
# Stage 3: Optimization (with recommended strategy)
|
||||
optimization_study = create_study(recommended_sampler)
|
||||
optimization_study.optimize(objective, n_trials=remaining)
|
||||
```
|
||||
|
||||
### 3. Comprehensive Documentation

|
||||
|
||||
### 4. Test Script
|
||||
|
||||
**File**: [`test_adaptive_characterization.py`](../test_adaptive_characterization.py)
|
||||
|
||||
**Purpose**: Validate that adaptive characterization behaves correctly for different problem types.
|
||||
|
||||
**Tests**:
|
||||
1. **Simple Smooth Quadratic**: Expected ~10-15 trials
|
||||
2. **Complex Multimodal (Rastrigin)**: Expected ~15-30 trials
|
||||
|
||||
**How to Run**:
|
||||
```bash
|
||||
python test_adaptive_characterization.py
|
||||
```
|
||||
|
||||
## Configuration
|
||||
|
||||
### Old Config (v1.0):
|
||||
```json
|
||||
{
|
||||
"intelligent_optimization": {
|
||||
"enabled": true,
|
||||
"characterization_trials": 15, // Fixed!
|
||||
"min_analysis_trials": 10,
|
||||
"stagnation_window": 10,
|
||||
"min_improvement_threshold": 0.001
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### New Config (v2.0):
|
||||
```json
|
||||
{
|
||||
"intelligent_optimization": {
|
||||
"enabled": true,
|
||||
"characterization": {
|
||||
"min_trials": 10,
|
||||
"max_trials": 30,
|
||||
"confidence_threshold": 0.85,
|
||||
"check_interval": 5
|
||||
},
|
||||
"landscape_analysis": {
|
||||
"min_trials_for_analysis": 10
|
||||
},
|
||||
"strategy_selection": {
|
||||
"allow_cmaes": true,
|
||||
"allow_gpbo": true,
|
||||
"allow_tpe": true
|
||||
}
|
||||
},
|
||||
"trials": {
|
||||
"n_trials": 50 // For optimization phase
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Intelligence Added
|
||||
|
||||
### Problem: How to determine characterization trial count?
|
||||
|
||||
**Old Approach (v1.0)**:
|
||||
- Fixed 15 trials for all problems
|
||||
- Wasteful for simple problems (only need ~10 trials)
|
||||
- Insufficient for complex problems (may need ~25 trials)
|
||||
|
||||
**New Approach (v2.0) - Adaptive Intelligence**:
|
||||
|
||||
1. **Metric Stability Detection**:
|
||||
```python
|
||||
# Track smoothness over last 3 analyses
|
||||
smoothness_values = [0.72, 0.68, 0.71] # Converging!
|
||||
smoothness_std = 0.017 # Low variance = stable
|
||||
if smoothness_std < 0.05:
|
||||
metric_stable = True # Confident in measurement
|
||||
```
|
||||
|
||||
2. **Complexity-Aware Sample Adequacy**:
|
||||
```python
|
||||
if multimodal and n_modes > 2:
|
||||
# Complex: need to sample multiple regions
|
||||
required = 10 + 5 * n_modes + 2 * dims
|
||||
elif smooth and unimodal:
|
||||
# Simple: quick convergence expected
|
||||
required = 10 + dims
|
||||
```
|
||||
|
||||
3. **Parameter Coverage Assessment**:
|
||||
```python
|
||||
# Check if explored enough of each parameter range
|
||||
for param in params:
|
||||
coverage = (explored_max - explored_min) / (bound_max - bound_min)
|
||||
# Need at least 50% coverage for confidence
|
||||
```
|
||||
|
||||
4. **Landscape Clarity**:
|
||||
```python
|
||||
# Clear classification = confident stopping
|
||||
if smoothness > 0.7 or smoothness < 0.3: # Very smooth or very rugged
|
||||
clarity_high = True
|
||||
if noise < 0.3 or noise > 0.7: # Low noise or high noise
|
||||
clarity_high = True
|
||||
```
|
||||
|
||||
### Result: Self-Adapting Characterization
|
||||
|
||||
**Simple Problem Example** (circular plate frequency tuning):
|
||||
```
|
||||
Trial 5: Landscape = smooth_unimodal (preliminary)
|
||||
Trial 10: Landscape = smooth_unimodal (confidence 72%)
|
||||
- Smoothness stable (0.71 ± 0.02)
|
||||
- Unimodal confirmed
|
||||
- Coverage adequate (60%)
|
||||
|
||||
Trial 15: Landscape = smooth_unimodal (confidence 87%)
|
||||
- All metrics converged
|
||||
- Clear classification
|
||||
|
||||
STOP: Confidence threshold met (87% ≥ 85%)
|
||||
Total characterization trials: 14
|
||||
```
|
||||
|
||||
**Complex Problem Example** (multimodal with 4 modes):
|
||||
```
|
||||
Trial 10: Landscape = multimodal (preliminary, 3 modes)
|
||||
Trial 15: Landscape = multimodal (confidence 58%, 4 modes detected)
|
||||
- Multimodality still evolving
|
||||
- Need more coverage
|
||||
|
||||
Trial 20: Landscape = rugged_multimodal (confidence 71%, 4 modes)
|
||||
- Classification stable
|
||||
- Coverage improving (55%)
|
||||
|
||||
Trial 25: Landscape = rugged_multimodal (confidence 86%, 4 modes)
|
||||
- All metrics converged
|
||||
- Adequate coverage (62%)
|
||||
|
||||
STOP: Confidence threshold met (86% ≥ 85%)
|
||||
Total characterization trials: 26
|
||||
```
|
||||
|
||||
## Benefits
|
||||
|
||||
### Efficiency
|
||||
- ✅ **Simple problems**: Stop early (~10-15 trials) → 33% reduction
|
||||
- ✅ **Complex problems**: Extend as needed (~20-30 trials) → Adequate coverage
|
||||
- ✅ **No wasted trials**: Only characterize as much as necessary
|
||||
|
||||
### Robustness
|
||||
- ✅ **Adaptive**: Adjusts to problem complexity automatically
|
||||
- ✅ **Confidence-based**: Only stops when metrics are stable
|
||||
- ✅ **Bounded**: Min 10, max 30 trials (safety limits)
|
||||
|
||||
### Transparency
|
||||
- ✅ **Detailed reports**: Explains all stopping decisions
|
||||
- ✅ **Metric tracking**: Full history of convergence
|
||||
- ✅ **Reproducibility**: All logged to JSON
|
||||
|
||||
## Example Usage
|
||||
|
||||
```python
|
||||
from optimization_engine.intelligent_optimizer import IntelligentOptimizer
|
||||
|
||||
# Create optimizer with adaptive characterization config
|
||||
config = {
|
||||
"intelligent_optimization": {
|
||||
"enabled": True,
|
||||
"characterization": {
|
||||
"min_trials": 10,
|
||||
"max_trials": 30,
|
||||
"confidence_threshold": 0.85,
|
||||
"check_interval": 5
|
||||
}
|
||||
},
|
||||
"trials": {
|
||||
"n_trials": 50 # For optimization phase after characterization
|
||||
}
|
||||
}
|
||||
|
||||
optimizer = IntelligentOptimizer(
|
||||
study_name="my_optimization",
|
||||
study_dir=Path("results"),
|
||||
config=config,
|
||||
verbose=True
|
||||
)
|
||||
|
||||
# Define design variables
|
||||
design_vars = {
|
||||
'parameter1': (lower1, upper1),
|
||||
'parameter2': (lower2, upper2)
|
||||
}
|
||||
|
||||
# Run Protocol 10 with adaptive characterization
|
||||
results = optimizer.optimize(
|
||||
objective_function=my_objective,
|
||||
design_variables=design_vars,
|
||||
n_trials=50, # Only for optimization phase
|
||||
target_value=115.0,
|
||||
tolerance=0.1
|
||||
)
|
||||
|
||||
# Characterization will stop at 10-30 trials automatically
|
||||
# Then optimization will use recommended algorithm for remaining trials
|
||||
```
|
||||
|
||||
## Testing Recommendations
|
||||
|
||||
1. **Unit Test**: Run `test_adaptive_characterization.py`
|
||||
- Validates adaptive behavior on toy problems
|
||||
- Expected: Simple problem stops early, complex problem continues
|
||||
|
||||
2. **Integration Test**: Run existing circular plate study
|
||||
- Should stop characterization at ~12-15 trials (smooth unimodal)
|
||||
- Compare with fixed 15-trial approach (should be similar or better)
|
||||
|
||||
3. **Stress Test**: Create highly multimodal FEA problem
|
||||
- Should extend characterization to ~25-30 trials
|
||||
- Verify adequate coverage of multiple modes
|
||||
|
||||
## Next Steps
|
||||
|
||||
1. **Test on Real FEA Problem**: Use circular plate frequency tuning study
|
||||
2. **Validate Stopping Decisions**: Review characterization logs
|
||||
3. **Benchmark Performance**: Compare v2.0 vs v1.0 trial efficiency
|
||||
4. **GP-BO Integration**: Add Gaussian Process Bayesian Optimization support
|
||||
5. **Two-Study Implementation**: Complete the transition to new optimized study
|
||||
