Abstract: A route planning method for large-scale capacitated arc routing problem is disclosed, belonging to the field of combinatorial optimization. The present disclosure firstly performs global optimization and proposes a low-cost decomposition optimization solution based on CARP, which pertinently preserves more excellent decompositions during iterations. And, the present disclosure is also applied to a local search stage, and proposes an improved route construction rule. In a process of route insertion, a problem of excessive useless cost caused by a vehicle with almost full load returning to a depot is considered. After improvement, local search can be carried out more effectively, thus further improving the solution quality. Compared with an existing route planning method, the present disclosure considers details and characteristics of CARP optimization problems in a more detailed manner, thus achieving solutions with a lower cost and improving the stability by about two to three times.

Abstract: A disclosed security broker receives a request message addressed to a message queue associated with an edge resource, identifies the message source, and leverages an authentication module to verify that the source has authorization to access the targeted message queue. The security broker may then deliver the request message to the targeted edge resource message queue. If the edge resource and security broker are physically isolated, the security broker may format the request message as a file, store the file to a storage device, and transfer the storage device to the edge resource, which may then process the file and upload the request message to the edge resource's message queue module. The security broker also monitors a response message from the edge resource, purges sensitive data from the response. If the broker and cloud resource are physically isolated, the response may be formatted and delivered as a file.

Abstract: A testing method accesses tracing data comprising a plurality of tracing records corresponding to a plurality of test cases executed on a target system. The target system includes a plurality of microservices configured in accordance with a REST API. A dynamic test analyzer accesses the tracing data and imports a definition of the REST API. The analyzer checks each tracing record for consistency with the API definition. Based on this checking of the tracing records, one or more coverage metrics may be calculated. If any one or more of the one or more coverage metrics fails to exceed a threshold coverage, a testing action may be required. In some cases, the testing action may be selected from either seeking additional coverage of the APIs included in the target system or seeking additional test result coverage.

The different selected tuck needle changes the connecting distance and the number of connections of the tuck, and the thickness of the spacer fabric and the arrangement density of the spacer yarns are changed by the action of the upper and lower surface layers of elastic yarns.

Abstract: A disclosed method for implementing containers in an information handling system generates, with a first non-privileged container, a request that is sent to a RESTful API. Whenever the API identifies a request requiring host access the API launches a second container, which is configured to operate in a privileged execution mode. The second container accesses the host and executes the requested actions. When the request completes, the first container resumes non-privileged execution, thereby confining privileged mode execution to a container that is only active during host interaction. The host access can be access required to: exchange data with the host, query the host for hardware information, and modify host configuration. The host may be implanted within a device featuring an HCI infrastructure. In one configuration, the host resides of one of multiple distinct nodes of an HCI appliance.

Abstract: A method for managing information handling resource versions includes maintaining one or more snapshots of one or more validated release versions for a group of components. Each validated release version indicates a component version for each component in the group. Each component version in a higher validated release version is required to be greater than or equal to a corresponding component version in a lower validated release version. Responsive to identifying an instance of the component group in an non-validated state, disclosed methods identify a lowest validated release version that “covers” the non-validated state, wherein a validated release version covers any state in which no component version is greater than its corresponding component version in the validated release version. The instance of the component group is updated to a validated release version that equals or exceeds the lowest validated version.
