Abstract: The present invention relates to request and messaging technology and in particular to mechanisms of efficiently processing such requests. A computing device receives, from the client, a plurality of requests, the plurality of requests including multiple first requests and multiple second requests, each of the first and second requests comprising request data. The computing device assigns, based on the request data, a respective request processing priority to each of the first and second requests, processes the first requests based on the assigned processing priorities, while the second requests remain pending for processing and determines whether to adapt the priorities of the second requests based on the request data of the second requests and/or response data generated for the multiple first requests.

Abstract: Methods, systems and computer program products for processing an input sequence of a plurality of function calls on at least one processor. Each function call of the plurality of function calls is associated with an abort probability, and each function call is also associated with a processing cost per function call on the basis of a number of processor instructions of the respective function call and the abort probability of the respective function calls. During processing of the function calls according to an input sequence, the abort probability for at least some of the function calls may be updated taking into consideration whether or not the processing of the respective function call caused an abort. The processing cost per function may be updated during processing, and an updated input sequence may be determined by rearranging the order of the function calls based on the processing cost.

Abstract: In one aspect thereof the exemplary embodiments provide a data processing system that includes at least one data processor; at least one memory connected with the data processor and that stores computer software that is executable by the at least one data processor; at least one database storing a plurality of fares and rules establishing conditions under which at least one of the fares can be applied; and an interface to at least one user and configured to receive from the user a fare inquiry. The data processor is configured with the computer software to cause the data processing system to receive a fare inquiry that contains at least one rule attribute, to perform a first search to determine rule data applicable to the at least one rule attribute, and to perform a second search using the rule data to retrieve a list of fares that are applicable to the rule data.
