Real-time multi-agent response based on a preference-based consensus
A method and associated systems provide real-time response to a request received from a real-time system like a self-driving vehicle or a device that communicates interactively with its environment. The response is selected from a set of candidate feasible responses by a group of computerized agents that each sort the feasible responses in order of that agent's specific preferences, based on that agent's particular priorities or expertise. The agents then reconcile their differences through an iterative procedure. During each iteration, each agent decides whether to retain its current preferences or to adopt the preferences of another agent. This decision is made by determining which preferences are most similar to that agent's own initial preferences, and by which preferences would be most useful in helping to achieve that agent's particular goals. When the agents reach consensus, the group's most-preferred response is returned quickly enough to provide real-time, interactive response. |

Pipeline performance improvement using stochastic dags
Software development pipeline tools construct pipelines by combining tools, files, and other resources, to build, integrate, test, deploy, or otherwise implement operational functionality in computing systems. Some pipelines are simple, but others are stochastic due to conditional execution, task addition or removal, resource availability randomness, and other causes. Some stochastic pipelines also include a hierarchy with multiple levels of task groupings, which adds complexity. Pipeline performance optimization uses critical paths, but critical paths are challenging to identify in stochastic pipelines. Tools and techniques are presented to automatically identify likely or actual critical paths and to indicate constituent critical tasks as improvement options for stochastic pipelines in software development or other industrial activities. Pipeline representations include directed acyclic graph data structures of constituent tasks. Computationally applying relevance filters helps identify performance improvement options based on historic execution data, without requiring the predefined task dependency information that stochasticity prevents. |

After the vapor-phase working fluid enters the condensation unit, the vapor-phase working fluid is distributed and condensed into liquid-phase working fluid. Then the liquid-phase working fluid is collected and then goes back to the evaporation unit. The length of the pipeline is shortened and the pipeline pressure is lowered to avoid interruption of heat dissipation circulation and failure in heat dissipation. |
