A method, system, and article for improving performance of a Boolean combination of at least two filters to a data stream. Stream processing is applied to an expression having two or more logical operators. As the data stream is processed, efficiency of the operators in the expression is evaluated. A sort algorithm is dynamically invoked to ensure that a more efficient operator precedes processing of a less efficient operator.

Method and apparatus for self optimizing data selection

A method, system, and article for automated processing of a data stream are provided. Stream processing is applied to a hierarchical self describing data stream. As the data stream is processed, some elements therein are associated with a selected path expression. The selected path expressions are ordered based upon the hierarchy, and a tree structure is created that corresponds to the hierarchy. Each leaf node of the tree is associated with a logical operator or an expression to be applied to data processed from the data stream to the leaf node.

Method and apparatus for automated processing of a data stream

A computer-implemented method for managing price information. Embodiments include receiving a mapping of interconnected components, identifying as a first subset components subject to a first fixed price agreement not subject to a second fixed price agreement that overlaps the first fixed price agreement, identifying as a second subset the components subject to the second fixed price agreement not subject to the first fixed price agreement, and identifying as a third subset the components subject to both the first fixed price agreement and the second fixed price agreement. The method also includes receiving a price change for a price associated with a component in one of the subsets of components, and distributing an offset of the price change to components in the other subsets of components.

System, method, and apparatus for managing price information with locking mechanisms

Methods, systems and computer program products for simplifying complex data stream problems involving feature extraction from noisy data. Exemplary embodiments include a method for processing a data stream, including applying multiple operators to the data stream, wherein an operation by each of the multiple operators includes retrieving the next chunk for each of set of input parameters, performing digital processing operations on a respective next chunk, producing sets of output parameters and adding data to one or more internal data stores, each internal data store acting as a data stream source.
