Multi-Agent System Foundation

Swarm architecture implements a foundational multi-agent system where agents operate as independent entities with specialized roles. The base Agent class establishes core functionality including message handling, task queuing, and state management essential for coordinated operations.

class Agent:
    def __init__(self, name: str, role: str):
        self.name = name
        self.role = role
        self.task_queue = []
        self.state = {}
        self.message_history = []
    
    def receive_task(self, task):
        self.task_queue.append(task)
        
    def process_message(self, message: dict):
        self.message_history.append(message)
        return self._handle_message(message)
    
    def _handle_message(self, message: dict):
        # Basic message processing logic
        response = {
            'sender': self.name,
            'status': 'processed',
            'content': f"Processed message from {message['sender']}"
        }
        return response

# Example usage
agent = Agent("agent_1", "analyzer")
message = {'sender': 'agent_2', 'content': 'analyze_data'}
response = agent.process_message(message)
print(f"Response: {response}")

Handoff Protocol Implementation

The Handoff protocol manages task transitions between agents, ensuring smooth workflow coordination. This implementation includes verification mechanisms to validate task completion and proper transfer between agent endpoints.

class HandoffProtocol:
    def __init__(self):
        self.active_handoffs = {}
        self.completion_registry = {}

    def initiate_handoff(self, source_agent: str, target_agent: str, task_data: dict):
        handoff_id = f"handoff_{len(self.active_handoffs)}"
        self.active_handoffs[handoff_id] = {
            'source': source_agent,
            'target': target_agent,
            'status': 'pending',
            'task_data': task_data
        }
        return handoff_id

    def complete_handoff(self, handoff_id: str, completion_status: bool):
        if handoff_id in self.active_handoffs:
            self.active_handoffs[handoff_id]['status'] = 'completed' if completion_status else 'failed'
            self.completion_registry[handoff_id] = completion_status
            return True
        return False

# Example usage
handoff = HandoffProtocol()
task = {'type': 'data_analysis', 'priority': 'high'}
handoff_id = handoff.initiate_handoff('agent_1', 'agent_2', task)
success = handoff.complete_handoff(handoff_id, True)

Task-Specific Agent Implementation

Specialized agents handle distinct responsibilities within the workflow. This implementation demonstrates a data processing agent with specific capabilities for handling numerical analysis tasks and preparing data for subsequent agents.

class DataProcessingAgent(Agent):
    def __init__(self, name: str):
        super().__init__(name, "data_processor")
        self.processed_data = []
        
    def process_data(self, raw_data: list):
        processed = []
        for item in raw_data:
            # Apply data transformation
            if isinstance(item, (int, float)):
                processed.append({
                    'original': item,
                    'normalized': item / max(raw_data),
                    'timestamp': time.time()
                })
        self.processed_data = processed
        return processed

    def get_processing_summary(self):
        return {
            'items_processed': len(self.processed_data),
            'last_processing': self.processed_data[-1] if self.processed_data else None
        }

# Example usage
processor = DataProcessingAgent("data_proc_1")
raw_data = [10, 20, 30, 40, 50]
results = processor.process_data(raw_data)
print(f"Processing summary: {processor.get_processing_summary()}")

Agent Communication System

A robust communication system enables agents to exchange information and coordinate activities. This implementation provides secure message passing with verification and delivery confirmation mechanisms.

class CommunicationSystem:
    def __init__(self):
        self.message_queue = {}
        self.registered_agents = set()
        
    def register_agent(self, agent_id: str):
        self.registered_agents.add(agent_id)
        self.message_queue[agent_id] = []
        
    def send_message(self, sender: str, recipient: str, content: dict):
        if recipient not in self.registered_agents:
            raise ValueError(f"Unknown recipient: {recipient}")
            
        message = {
            'id': str(uuid.uuid4()),
            'sender': sender,
            'timestamp': time.time(),
            'content': content
        }
        self.message_queue[recipient].append(message)
        return message['id']
        
    def fetch_messages(self, agent_id: str):
        if agent_id not in self.registered_agents:
            return []
        messages = self.message_queue[agent_id]
        self.message_queue[agent_id] = []
        return messages

# Example usage
comm_system = CommunicationSystem()
comm_system.register_agent("agent_1")
comm_system.register_agent("agent_2")
msg_id = comm_system.send_message("agent_1", "agent_2", {"action": "process_data"})
messages = comm_system.fetch_messages("agent_2")

Workflow Orchestrator

The Workflow Orchestrator manages the execution flow between multiple agents, handling task distribution and monitoring agent states. It implements a priority-based task scheduler and ensures proper sequencing of operations across the agent network.

class WorkflowOrchestrator:
    def __init__(self):
        self.agents = {}
        self.workflow_state = {}
        self.task_dependencies = {}
        
    def register_agent(self, agent_id: str, agent_instance: Agent):
        self.agents[agent_id] = agent_instance
        self.workflow_state[agent_id] = 'idle'
        
    def create_workflow(self, tasks: list, dependencies: dict):
        workflow_id = str(uuid.uuid4())
        self.task_dependencies[workflow_id] = {
            'tasks': tasks,
            'dependencies': dependencies,
            'status': 'pending'
        }
        return workflow_id
        
    def execute_workflow(self, workflow_id: str):
        if workflow_id not in self.task_dependencies:
            raise ValueError("Invalid workflow ID")
            
        workflow = self.task_dependencies[workflow_id]
        completed_tasks = set()
        
        while len(completed_tasks) < len(workflow['tasks']):
            for task in workflow['tasks']:
                if self._can_execute_task(task, completed_tasks, workflow['dependencies']):
                    self._assign_task(task)
                    completed_tasks.add(task)
                    
        return {'workflow_id': workflow_id, 'status': 'completed'}
    
    def _can_execute_task(self, task: str, completed: set, dependencies: dict):
        return all(dep in completed for dep in dependencies.get(task, []))
        
    def _assign_task(self, task: str):
        available_agent = self._find_available_agent()
        if available_agent:
            self.workflow_state[available_agent] = 'busy'
            self.agents[available_agent].receive_task(task)

# Example usage
orchestrator = WorkflowOrchestrator()
orchestrator.register_agent('agent_1', Agent('agent_1', 'processor'))
orchestrator.register_agent('agent_2', Agent('agent_2', 'analyzer'))

workflow = orchestrator.create_workflow(
    tasks=['process_data', 'analyze_results'],
    dependencies={'analyze_results': ['process_data']}
)
result = orchestrator.execute_workflow(workflow)

Agent State Management

The state management system maintains consistency across the multi-agent environment by tracking agent states, task progress, and system-wide configurations while providing atomic operations for state updates.

class StateManager:
    def __init__(self):
        self._states = {}
        self._locks = {}
        self._state_history = []
        
    def register_agent_state(self, agent_id: str, initial_state: dict):
        self._states[agent_id] = initial_state
        self._locks[agent_id] = threading.Lock()
        self._log_state_change(agent_id, None, initial_state)
        
    def update_state(self, agent_id: str, updates: dict):
        if agent_id not in self._states:
            raise KeyError(f"Unknown agent: {agent_id}")
            
        with self._locks[agent_id]:
            old_state = copy.deepcopy(self._states[agent_id])
            self._states[agent_id].update(updates)
            self._log_state_change(agent_id, old_state, self._states[agent_id])
            
    def get_state(self, agent_id: str):
        return copy.deepcopy(self._states.get(agent_id))
        
    def _log_state_change(self, agent_id: str, old_state: dict, new_state: dict):
        self._state_history.append({
            'timestamp': time.time(),
            'agent_id': agent_id,
            'old_state': old_state,
            'new_state': new_state
        })
        
    def get_state_history(self, agent_id: str = None):
        if agent_id:
            return [entry for entry in self._state_history if entry['agent_id'] == agent_id]
        return self._state_history

# Example usage
state_manager = StateManager()
state_manager.register_agent_state('agent_1', {'status': 'idle', 'tasks_completed': 0})
state_manager.update_state('agent_1', {'status': 'processing', 'tasks_completed': 1})
current_state = state_manager.get_state('agent_1')
history = state_manager.get_state_history('agent_1')

Real-time Monitoring System

This comprehensive monitoring system tracks agent performance, system health, and workflow progress in real-time. It implements metrics collection, performance analysis, and alert generation for system administrators.

class MonitoringSystem:
    def __init__(self):
        self.metrics = defaultdict(list)
        self.alerts = []
        self.performance_thresholds = {
            'response_time': 1.0,  # seconds
            'queue_size': 100,
            'error_rate': 0.05
        }
        
    def record_metric(self, agent_id: str, metric_type: str, value: float):
        timestamp = time.time()
        self.metrics[agent_id].append({
            'type': metric_type,
            'value': value,
            'timestamp': timestamp
        })
        self._check_thresholds(agent_id, metric_type, value)
        
    def get_agent_metrics(self, agent_id: str, metric_type: str = None):
        agent_metrics = self.metrics.get(agent_id, [])
        if metric_type:
            return [m for m in agent_metrics if m['type'] == metric_type]
        return agent_metrics
        
    def _check_thresholds(self, agent_id: str, metric_type: str, value: float):
        threshold = self.performance_thresholds.get(metric_type)
        if threshold and value > threshold:
            self._generate_alert(agent_id, metric_type, value, threshold)
            
    def _generate_alert(self, agent_id: str, metric_type: str, value: float, threshold: float):
        alert = {
            'timestamp': time.time(),
            'agent_id': agent_id,
            'metric_type': metric_type,
            'value': value,
            'threshold': threshold,
            'severity': 'high' if value > threshold * 1.5 else 'medium'
        }
        self.alerts.append(alert)
        return alert

# Example usage
monitor = MonitoringSystem()
monitor.record_metric('agent_1', 'response_time', 0.8)
monitor.record_metric('agent_1', 'queue_size', 120)
metrics = monitor.get_agent_metrics('agent_1')
print(f"Active alerts: {len(monitor.alerts)}")

Error Handling and Recovery

A robust error handling system ensures system reliability through sophisticated error detection, logging, and recovery mechanisms. This implementation provides automatic error classification and appropriate recovery strategies for different failure scenarios.

class ErrorHandler:
    def __init__(self):
        self.error_log = []
        self.recovery_strategies = {
            'task_failure': self._handle_task_failure,

        }
        self.consecutive_failures = defaultdict(int)
        
    def handle_error(self, agent_id: str, error_type: str, error_data: dict):
        error_entry = {

            'agent_id': agent_id,
            'type': error_type,
            'data': error_data,
            'recovery_attempted': False
        }
        self.error_log.append(error_entry)
        
        if error_type in self.recovery_strategies:
            recovery_result = self.recovery_strategies[error_type](agent_id, error_data)
            error_entry['recovery_attempted'] = True
            error_entry['recovery_result'] = recovery_result
            
        self._update_failure_count(agent_id, error_type)
        return error_entry
    
    def _handle_task_failure(self, agent_id: str, error_data: dict):
        retry_count = error_data.get('retry_count', 0)
        if retry_count < 3:
            return {
                'action': 'retry',
                'delay': 2 ** retry_count  # Exponential backoff

        }
    
    def _handle_resource_exhaustion(self, agent_id: str, error_data: dict):
        return {
            'action': 'scale_resources',
            'resource_type': error_data.get('resource_type')
        }
    
    def _update_failure_count(self, agent_id: str, error_type: str):
        key = f"{agent_id}:{error_type}"
        self.consecutive_failures[key] += 1
        if self.consecutive_failures[key] >= 5:
            self._trigger_circuit_breaker(agent_id, error_type)
    
    def _trigger_circuit_breaker(self, agent_id: str, error_type: str):

    'task_failure',
    {'task_id': 'process_data', 'retry_count': 1}
)
print(f"Error handling result: {error_result}")

Agent Load Balancing

The load balancing system optimizes resource utilization by dynamically distributing tasks across available agents based on their current workload, capacity, and performance metrics.

class LoadBalancer:
    def __init__(self):
        self.agents = {}
        self.workload_history = defaultdict(list)
        self.performance_metrics = {}
        
    def register_agent(self, agent_id: str, capacity: float):

        agent_info = self.agents[agent_id]
        load_factor = 1 - (agent_info['current_load'] / agent_info['capacity'])
        performance_score = self.performance_metrics.get(agent_id, {}).get('score', 0.5)
        return load_factor * 0.7 + performance_score * 0.3
        
    def _update_agent_load(self, agent_id: str, task: dict):

            'timestamp': time.time(),
            'load': self.agents[agent_id]['current_load']
        })

# Example usage
balancer = LoadBalancer()
balancer.register_agent('agent_1', capacity=1.0)
balancer.register_agent('agent_2', capacity=0.8)

task = {'id': 'task_1', 'load_estimate': 0.3}
assigned_agent = balancer.assign_task(task)
print(f"Task assigned to: {assigned_agent}")

Agent Self-Optimization System

A sophisticated mechanism enabling agents to autonomously improve their performance through runtime analysis and dynamic parameter adjustment. The system implements reinforcement learning concepts for continuous optimization of agent behavior.

class SelfOptimizer:
