Engineering Contradiction Analysis
1Ease of operation
If simple on-board processing procedures are used to control autonomous agents with limited processing capabilities, then the autonomous units can operate independently, but the ability to achieve complex group behaviors and efficient large-scale control is reduced
Solution Approach 1:
The control system is segmented into two parts: simple local processing rules executed by each autonomous agent, and a centralized spectral graph analysis component that processes global swarm state. This segmentation allows agents to operate independently with simple processing while the centralized system achieves efficient large-scale control through spectral analysis of the interaction graph.
Solution Approach 2:
The patent introduces an intermediary processing layer that translates complex control objectives into simple local interaction rules for agents. This intermediary layer (the spectral graph analysis system) acts as a mediator between the simple on-board processing capabilities and the desired complex group behaviors, enabling both autonomous operation and efficient large-scale control.
2Adaptability or versatility
If complex group behaviors are achieved by combining microscopic behaviors of individual entities, then desired swarm activities can be realized, but the computational complexity and difficulty of controlling the swarm increases
Solution Approach 1:
The patent replaces traditional mechanical control approaches with spectral graph analysis. Instead of directly controlling each agent through complex mechanical or electronic control systems, the invention uses mathematical spectral analysis of the interaction graph to infer and control emergent group behaviors, significantly reducing control system complexity while maintaining versatility.
Solution Approach 2:
The patent changes the control parameters from individual agent states to spectral properties of the interaction graph. By transforming the control problem from managing individual microscopic behaviors to manipulating graph spectral characteristics, the system achieves complex group behaviors with simpler control mechanisms.
3Measurement precision
If spectral graph analysis is used to identify approximate cliques corresponding to objects participating in an activity, then detection of desired group behaviors becomes possible, but the processing requirements and system complexity increase
Solution Approach 1:
The patent applies partial spectral analysis by focusing on specific eigenvalues and eigenvectors that are most relevant to detecting group behaviors, rather than computing the complete spectral decomposition. This partial action approach achieves sufficient detection accuracy while reducing processing requirements and system complexity.
Solution Approach 2:
The patent extracts only the essential spectral features (specific eigenvalues and eigenvectors) needed for detecting desired group behaviors, rather than processing the entire spectral spectrum. This extraction approach maintains measurement precision for behavior detection while minimizing processing requirements and system complexity.

AI summary
A system for controlling a swarm that includes a plurality of autonomous objects may include a processing system and a controller. The processing system may compute the primitives to be applied to each pair of objects in the swarm, and may combine the primitives to generate higher-level primitives. The processing system may generate a graph of the computed primitives, and identify the cliques in the graph. The controller may cause the primitives to be applied between each pair of objects in the swarm, and cause each object to maximize its respective set of primitives so as to induce the desired group behavior. The controller may detect the desired group behavior in the swarm by monitoring the primitives computed by the processing system and the cliques identified by the processing system.
