  • Patent number: 6088510
    Abstract: A computer object processing system for, during selected iterations, generating an object, such as an expression defining an image. During an initial iteration, a predetermined number of seed objects are generated, each seed object defining an object for the initial iteration. During each successive iteration, a predetermined number of mutated objects are generated (i) in response to an operator selected one of the seed objects during the initial iteration and (ii) in response to a an operator selected object during each iteration after the initial iteration. During each iteration one of the seed objects or one of the mutated objects is selected for use in generating a mutated object during a subsequent iteration.

  • Patent number: 6064971
    Abstract: A method to operate a computerized adaptive knowledge base. The contents and organization of the adaptive knowledge base evolve based on the contributions and evaluations of a user community. Whether a particular set of contents or an alternative organization is preserved for future iterations is a function of user evaluations, taking into account the amounts of information and the relative importance of content vis-a-vis organization. Items of the adaptive knowledge base which are as yet unevaluated by a particular user are ranked by estimating that user's evaluations, based on other items for which evaluations are available to compare with other users. For example, evaluations are estimated from regressions with other users, weighted by functions of the correlation coefficients, the number of observations in common, and the significance of those observations for the particular user in the sense that their evaluation differs from the mean evaluation.

  • Patent number: 6049672
    Abstract: A microprocessor operates in response to microinstructions stored in a read only memory. A patch table stores a indication of patch microinstructions stored in cache memory. This cache memory caches data and/or macroinstructions for the microprocessor. Each new microaddress is compared with the patch table entries. If there in no match, then a multiplexer selects the microinstruction recalled from that microinstruction address within the microinstruction read only memory. If there is a match, then a corresponding patch microinstruction is recalled from the cache memory. The multiplexer selects this patch microinstruction. The microprocessor operates under the control of the selected microinstruction. This technique enables a fix of faulty microinstructions in the field, by supplying the computer user with the patch microinstructions. Using a portion of the cache memory to store the patch microinstructions eliminates any problem with specifying too large or too small a memory for patch microinstructions.

  • Patent number: 6044219
    Abstract: A utility with which a programmer can generate or alter computer code for a calendaring function, and test the code prior to compilation. Entering the program in edit mode, the programmer locates a portion of the program where code for a calendaring function is to be generated or altered, and invokes the date logic generator. The date logic generator provides an initial window with a choice of calendaring functions, and upon selecting a calendaring function, a parameters window displaying a number of first-level parameters for that function is provided. Depending on the specification of the values of the first-level parameters, sub-windows with second-level parameters may be provided. And, in general, depending on the specification of the values of the n-level parameters, (n+1)-level parameters may be provided in sub-windows. The parameters provided at any instant are only those which have already been specified or those that require specification.
