Judgment Enhancement Engine
Enhance AI agent decision-making under uncertainty through recursive Monte Carlo lookahead simulation, risk-adjusted utility, and historical reflection.
Quick Start
# Run built-in GridWorld demo
python skills/judgment-enhancement-engine/engine.py
# One-click setup
bash skills/judgment-enhancement-engine/scripts/setup.sh # Linux/macOS/WSL
skills\judgment-enhancement-engine\scripts\setup.bat # Windows
Core Usage
from engine import JudgmentEnhancementEngine, JudgmentResult
# 1. Define your world model (must implement WorldModel protocol)
class MyWorldModel:
def get_possible_outcomes(self, state, action):
# Returns [(next_state, probability, reward), ...]
...
def is_terminal(self, state):
...
def get_legal_actions(self, state):
...
# 2. Define objective function
class MyObjective:
def evaluate(self, state):
return float_score # higher = better
# 3. Create engine
engine = JudgmentEnhancementEngine(
world_model=MyWorldModel(),
objective=MyObjective(),
risk_tolerance=0.5, # 0=extreme risk-averse, 1=risk-neutral
lookahead_depth=3, # recursion depth
simulation_breadth=4, # max actions evaluated per level
use_greedy_rollout=True, # True=greedy (accurate), False=uniform (fast)
max_compute_time_sec=2.0 # timeout protection
)
# 4. Make a judgment
result = engine.enhance_judgment(current_state)
print(f"Best action: {result.best_action}")
print(f"Confidence: {result.confidence:.2f}")
print(f"Reasoning: {result.reasoning}")
# 5. Record actual outcome (for historical correction)
engine.record_outcome(state, action, actual_utility)
# 6. Optional: clear history
engine.clear_history()
