Abstract: A reaction pathfinder system can leverage historical chemical reaction data and determine a synthesis route in a reaction network. The reaction pathfinder system can account for various performance criteria of chemical reactions such as a highest yield for a molecule or a minimal number of reaction steps. A reaction pathfinder system receives a user request for a synthesis route including one of a user-specified molecule or a user-specified reaction. The reaction pathfinder system may then query a reaction network that has various synthesis routes and represents reactions of reactants to produce respective molecules. The reaction network may be composed of molecule nodes and reaction nodes. The reaction pathfinder system determines, using the reaction network, the synthesis route from the synthesis routes to fulfill the user's request.

Abstract: A computer-implemented method for modifying image data, the method including: loading unmodified image data; detecting at least two alphanumeric characters in an image represented by the loaded image data; selecting one or more of the detected alphanumeric characters, wherein the number of selected alphanumeric characters is smaller than the total number of detected alphanumeric characters; modifying the loaded image data by removing one or more character sections of the loaded image data, wherein each character section corresponds to an area of a selected alphanumeric character; storing the modified image data. Also provided is a corresponding data processing system, computer program product and computer-readable storage medium.

Abstract: A computer-implemented method for optical character recognition and corresponding data processing apparatus, computer program and computer-readable medium. The method includes the following: receiving image data of an input image having one or more characters and applying one or more data processing operations to the received image data, wherein at least one of the data processing operations is configured to return the one or more characters of the input image, wherein each data processing operation is selected from a predefined set of available data processing functions according to a processing configuration, wherein the available data processing functions are precompiled functions, and wherein the processing configuration can be changed at runtime.
