    Abstract: A solution is calculated using a tree search within a limited calculation time. A solution searching device that performs solution search using a search tree includes a search tree expanding unit that creates a node based on options until a stop condition is satisfied, an evaluation calculation unit that calculates an evaluation value for an leaf node using a first evaluation method, and a search solution determination unit that sequentially updates an evaluation value of an upper node based on an evaluation value of a lower node to determine a search solution.

    Abstract: An evaluation apparatus includes: a processor; a memory; and an interface configured to receive data output by devices. The processor being configured to: receive action indicators including indicative data representing at least one physical quantity measured by a device and indicative data representing at least one specific of an action performed by the device through the interface; store the received action indicators to the memory; presume the action of the device by finding a match through comparing the received action indicators with templates each specifying a combination of items of indicative data required to presume an action of the devices; extract indicative data required to evaluate the presumed action from the received action indicators; and evaluate quality of the presumed action based on the extracted indicative data.

    Abstract: In a network system including a plurality of pieces of network equipment, detection of a piece of network equipment in which an abnormality occurs is made possible. In the network system including the pieces of network equipment, index values indicating operation states of the pieces of network equipment such as data-plane index values are acquired from the respective pieces of network equipment via communication media, high-frequency components of the acquired index values are calculated, and the abnormality in the piece of network equipment is detected based on a correlation of the high-frequency components.

    Abstract: Disclosed is an information collection and display system in which a data generation device that generates site data and a transaction data accumulation unit that stores the site data are connected. The information collection and display system includes an association data accumulation unit that stores association data defining association of each of a plurality of pieces of information included in the site data; an association data search unit that searches for second information associated with first information included in the plurality of pieces of information, on the basis of the association data; and a user interface that displays a connection relation of the plurality of pieces of information associated by the association data. The association data search unit searches for the second information associated with the first information displayed on the user interface and displays the first information and the second information on the user interface with the connection relation of the plurality of pieces of information.
