Multi-Agent Planning (MAP) is the computational process by which a group of autonomous agents collaboratively formulates a sequence of actions—potentially distributed and interdependent—to achieve a set of shared or individual goals. Unlike single-agent planning, MAP must address challenges of partial observability, decentralized control, and the need for coordination to manage dependencies and avoid conflicts between agents' proposed actions. It sits at the intersection of automated planning, game theory, and multi-agent systems.

What is Multi-Agent Planning (MAP)?
Multi-Agent Planning is a subfield of artificial intelligence and distributed systems focused on the collaborative generation of action sequences by multiple autonomous entities.
MAP problems are formally modeled using frameworks like Decentralized Partially Observable Markov Decision Processes (Dec-POMDPs) and Distributed Constraint Optimization Problems (DCOPs). Solutions employ coordination patterns such as the Contract Net Protocol for task allocation or Partial Global Planning (PGP) for plan merging. The output is a joint policy or plan that specifies each agent's actions over time, balancing individual rationality with collective utility, which is critical for applications like autonomous fleets, smart grids, and distributed robotics.

Core Characteristics of Multi-Agent Planning (MAP)
Multi-Agent Planning (MAP) is the process by which a group of agents collaboratively formulates a sequence of actions to achieve shared or individual goals. Its core characteristics distinguish it from single-agent planning and define its unique challenges and solutions.
01
Distributed Problem Solving
MAP inherently involves decentralized computation and partial observability. Unlike a single, omniscient planner, each agent typically has:
- A local view of the global state.
- Private goals or a partial understanding of the shared objective.
- Limited communication bandwidth with other agents.
This distribution necessitates algorithms for plan merging, conflict detection, and information sharing to build a coherent global plan from local contributions. Frameworks like Decentralized POMDPs (Dec-POMDPs) formally model these challenges.

How Does Multi-Agent Planning Work?
Multi-Agent Planning (MAP) is the collaborative process by which a group of autonomous agents formulates a sequence of actions to achieve shared or individual goals.
Multi-Agent Planning (MAP) is the collaborative process by which a group of autonomous agents formulates a sequence of actions to achieve shared or individual goals. It extends classical single-agent planning into a distributed context, requiring agents to reason about interdependent actions, partial observability, and potential resource conflicts. The core challenge is generating a joint plan—a coordinated set of individual agent plans—that is both globally consistent and locally executable, often using formal models like Decentralized Partially Observable Markov Decision Processes (Dec-POMDPs) or Distributed Constraint Optimization Problems (DCOPs).
Execution typically involves iterative coordination protocols such as the Contract Net Protocol for task allocation or Partial Global Planning (PGP) for plan merging. Agents must communicate intentions, negotiate over resources, and resolve conflicts using mechanisms like auction-based coordination or argumentation-based negotiation. The resulting system exhibits emergent coordination, where coherent global behavior arises from local decisions, enabling complex problem-solving in domains like logistics, robotics, and smart grid management without a central controller.

Frequently Asked Questions
Multi-Agent Planning (MAP) is the process by which a group of autonomous agents collaboratively formulates a sequence of actions to achieve shared or individual goals. This FAQ addresses core concepts, mechanisms, and applications of MAP.
Multi-Agent Planning (MAP) is the computational process where multiple autonomous agents collaboratively generate a sequence of actions—a plan—to achieve a set of shared or individual goals, often in environments with distributed control, partial observability, and interdependent actions. It works by integrating techniques from automated planning, distributed systems, and game theory. Agents must reason about the actions of others, manage goal dependencies, and resolve potential conflicts. Core mechanisms include formulating the problem as a Decentralized Partially Observable Markov Decision Process (Dec-POMDP) or a Distributed Constraint Optimization Problem (DCOP), and then using algorithms for plan merging, coordination graph optimization, or negotiation to synthesize a coherent joint or coordinated plan from distributed local perspectives.
