Abstract: Disclosed are systems and methods for adjusting the encoding/ordering of parts of a satisfiability modulo theories (“SMT”) problem indicated in an SMT configuration and/or optimizing the SMT solver configuration of an SMT solver to reduce the processing time needed to process the SMT problem using the SMT solver. For example, the order of parts of an SMT problem may be rearranged to reduce a processing time of the SMT problem. Likewise, the configuration options selected for an SMT solver may be adjusted to reduce the processing time required to process an SMT problem.

Abstract: Techniques are described for executing satisfiability modulo theories (SMT) solvers in a “shadow” system configuration where input queries are provided to a primary SMT solver system and additionally to one or more secondary SMT solver systems. SMT solver systems can be used by cloud providers and in other computing environments to analyze the implications of configured user account policies defining permissions with respect to users' computing resources and associated actions within a computing environment, to help ensure the security of computing resources and user data, etc. The results generated by a primary SMT solver system can be provided to one or more secondary SMT solver systems, where each of the secondary SMT systems can comprise different system components or different versions of system components, to assess the correctness of the primary SMT solver system, to compare performance metrics, among other possible types of analyses.

Abstract: Intrusion detection systems and methods monitor legal control messages in an operational control system to detect subtly malicious sequences of control messages with undesirable emergent effects on devices in the operational control system. A message provenance component may investigate system-level correlations between messages rather than detecting if individual messages are anomalous. A semantic fuzzing component may search, based on the operational effect of candidate message sequences, the space of legal messages for sequences that cause actual harm. Behavior oracles may be used to test message sequences to identify sequences that induce drift towards a failure state. The intrusion detection system is able to prevent harm and disruption arising from control messages that individually appear legitimate and benign but that, in combination with other messages, can cause undesirable outcomes.

Abstract: Described herein are platforms, systems, media, and methods for measuring a space by launching an active augmented reality (AR) session on a device comprising a camera and at least one processor; calibrating the AR session by establishing a fixed coordinate system, receiving a position and orientation of one or more horizontal or vertical planes in the space in reference to the fixed coordinate system, and receiving a position and orientation of the camera in reference to the fixed coordinate system; constructing a backing model; providing an interface allowing a user to capture at least one photo of the space during the active AR session; extracting camera data from the AR session for the at least one photo; extracting the backing model from the AR session; and storing the camera data and the backing model in association with the at least one photo.

Abstract: This disclosure describes techniques that include generating, based on a description of a scene, a movie or animation that represents at least one possible version of a story corresponding to the description of the scene. This disclosure also describes techniques for training a machine learning model to generate predefined data structures from textual information, visual information, and/or other information about a story, an event, a scene, or a sequence of events or scenes within a story. This disclosure also describes techniques for using GANs to generate, from input, an animation of motion (e.g., an animation or a video clip). This disclosure also describes techniques for implementing an explainable artificial intelligence system that may provide end users with information (e.g., through a user interface) that enables an understanding of at least some of the decisions made by the AI system.

Abstract: A method, apparatus and system for automated verification of a smart contract on a blockchain include translating operating properties of a smart contract annotated with contract specifications at a source code level into verification conditions in an intermediate verification language, discharging the verification conditions using an SMT solver, and reporting results of the discharged verification conditions, such as successes and failures of the discharged verification conditions. The translating can include mapping statements of the smart contract to statements of the intermediate verification language and mapping expressions of the smart contract to expressions of the intermediate verification language.

Abstract: An apparatus and method facilitate sale of an invoice from a seller to a buyer. An invoice is received, by the apparatus, for sale by a seller, the invoice to be paid by a payer after the sale of the invoice to a buyer. The apparatus accesses a blockchain associated with both the seller and the buyer of the invoice, the blockchain storing a ledger of past invoice sales by the seller and past invoice purchases by the buyer. The apparatus generates a first rating score for the seller and a second rating score for the payer, the first and second rating scores being based on the ledger of past invoice sales by the seller stored on the blockchain and past invoice payments by the payer, respectively. The apparatus sends an offer to a buyer to sell the invoice at a discounted price.
