Methods and systems for processing graphs using distributed memory and set operations

Systems and methods for operating a database using distributed memory and set operations, and for evaluating graphs stored in the database. Any system may be represented as a graph structure having nodes and edges. The graph structure is stored in a distributed memory system using a key / value schema wherein each node is stored as a key and a set of neighbor nodes is stored as the corresponding value. A short path from one node to another may be determined by traversing the graph in stages, moving outward from each node in stages until common midpoint nodes are found indicating connections between the nodes. When the midpoint nodes are found, the paths connecting the nodes may be reconstructed.

Techniques for network policies analysis in container frameworks

Techniques are disclosed for query processing system that can, when queried, generate a result related to one or more connectivity paths and / or one or more network security rules. Network security rules and connectivity paths may be stored in corresponding data structures (e.g., sets of attributes) that may be utilized with a number of set operations. The user may issue a query requesting the system to apply a rule to a path, a set of rules to a set of paths, to identify if one set of rule(s) are equivalent to another set of rule(s), and the like. Utilizing this query processing system can enable a user to identify effects of one or more network rules with respect to traffic being allowed or restricted along particular connectivity paths between components of the system.

Progressive setting method for PID parameters

The invention provides a progressive setting method for PID parameters. The progressive setting method comprises the steps: determining an optimization problem expression corresponding to a controlledsystem and a reference system model expression corresponding to the controlled system based on a controlled system structure; determining a PID parameter selection range as a parameter setting constraint condition; determining an initial value of an optimization target parameter, and judging whether PID parameter setting operation is triggered or not based on the numerical relationship between the current parameter value and the target parameter value: if the PID parameter setting operation is triggered, circularly solving the optimization problem expression based on the reference system model expression under the parameter setting constraint condition. PID controller parameters are directly set based on process input and output data, so a modeling process is not needed; therefore, modelerrors caused by modeling, a large amount of test data required by modeling and the time cost of test modeling are avoided. Meanwhile, only a small amount of test data and computing resources are needed, so the generation is not greatly disturbed in the setting process, and the method is suitable for online setting of the PID controller.
