  • Patent number: 11235224
    Abstract: A method, system, and computer program product algorithmically analyzes scoring data from a competitive event where the scoring, determined by a plurality of evaluators, is based on subjective criteria. The method receives, and/or determines a scale factor associated with each evaluator. The method adjusts scores awarded by each evaluator, based on respectively corresponding scale factors, to arrive at normalized scores. The method, thereby minimizes influences of biases associated with the evaluators.

  • Patent number: 10747925
    Abstract: A system and method of performing variable accuracy incremental timing analysis in integrated circuit development includes generating a timing graph for interconnected components. The timing graph represents each pin as a node and each interconnection as an arc. A first node or arc is selected. First-level timing values are obtained for the first node or arc using a first timing model that provides a first level of accuracy. n timing models with corresponding n levels of accuracy are pre-selected. The first-level timing values are copied as second-level timing values and as timing values for every other one of the n levels of accuracy for the first node or arc. A second node or arc downstream from the first node or arc is selected. Second-level timing values for the second node or arc are obtained using a second timing model that provides a second level of accuracy.
