Padrões Derivados Problem(s)SolutionPattern Spatial Source to Destination Routing, Task Recruitment, Relation Identification, Integration of various information Sources Agents explicitly search for goals, tasks, or related items and drop pheromones to form paths for other agents to follow to the goal or task. Reinforcement of an existing path by other agents can be seen as a reinforcement of the relation between source and destination. Evaporation, Aggregation, and Propagation keep the pheromones up-to- date and support integration of various information sources. Digital Pheromone Paths Spatial Movement, Pattern Formation, Structure Formation, Routing, Integration of Contextual Information Spatial, contextual, and coordination-related information is automatically spread/propagated by the environment as multiple computational fields. Agents simply follow the waveform of these fields to achieve the coordination task, no explicit exploration is needed. The spatial information comes to the agents instead of agents explicitly searching. Gradient Fields Resource Allocation in general (resource=task, power, bandwidth, space, time, etc.), Integration of resource Usage/Need Information A virtual market where resource users sell and buy resource usage with virtual currency. The price evolves according to the market dynamics and indicates a high (high price) or low (low price) demand. This information is used by agents to decide on using the resource or not. Economic market theory states that the prices converge to a stable equilibrium. Market-based Coordination Team-formation, Trust and reputation Agents put and modify tags on other agents and a team is formed by only collaborating with agents with the same tag or some other condition. If tags indicate how well agents behaved in collaborations with others then trust and reputation information can be available. Tags Synchronisation, Resource Allocation A capability or a resource is represented by a token. Synchronisation happens because only the holder can use the resource or executes a certain capability. Tokens can be passed among agents to allocate the resource or capability to others. Tokens ………
