Symbolic execution identifies possible execution paths of a computer program or method, each having certain constraints over the input values. The symbolic execution also records updates of memory locations, e.g. updates of the fields of symbolic objects in the heap of an object oriented program, involving a description of the previous heap, the updated symbolic object, a field identification, and a newly assigned symbolic value.

Apparatus and method for optimizing the performance of x87 floating point addition instructions in a microprocessor
A microprocessor having a Precision Control (PC) field, an instruction dispatcher, and a Floating Point unit (FPU). The FPU receives an FP Add instruction from the instruction dispatcher, and generates a sum from its addends. The FPU determines whether any conditions exist in the addends with respect to their contribution to a rounding determination and relative to the PC field. If none of the conditions exists, the FPU makes the rounding determination based on the smaller addend and the PC field, and selectively rounds the sum based on the rounding determination. If any conditions exist, the FPU saves the sum and rounding information derived from the addends, and signals the instruction dispatcher to re-dispatch the instruction. On re-dispatch, the FPU makes the rounding determination based on the saved rounding information and the PC field, and selectively rounds the sum based on the rounding determination. |

Document retrieval system and document retrieval method
A document retrieval is performed with similarities between documents in numeric data taken into consideration. To this end, generated is a set E of intervals in which each element of a set D of numeric values representing a feature A is included in any one of the intervals. Each numeric value in each document is indexed by assigning, with 1, an interval including an element x of the set D, and with 0, an interval without the element x. Each document data including numeric values is indexed by indexing its text part with term frequencies, and by indexing its numeric-value part with the above-described numeric value indexing scheme.

Nonlinear function approximation over high-dimensional domains
An algorithm is disclosed for constructing nonlinear models from high-dimensional scattered data. The algorithm progresses iteratively adding a new basis function at each step to refine the model. The placement of the basis functions is driven by a statistical hypothesis test that reveals geometric structure when it fails. At each step the added function is fit to data contained in a spatio-temporally defined local region to determine the parameters, in particular, the scale of the local model. The proposed method requires no ad hoc parameters. Thus, the number of basis functions required for an accurate fit is determined automatically by the algorithm. The approach may be applied to problems including modeling data on manifolds and the prediction of financial time-series. The algorithm is presented in the context of radial basis functions but in principle can be employed with other methods for function approximation such as multi-layer perceptrons. |

Control apparatus of internal combustion engine
This control apparatus estimates a full combustion correspondence period CP, which is the period from an ignition timing SA to a combustion completion time CAe, and controls a VVT advancement amount (burnt gas quantity, overlap period, intake valve open timing) such that the estimated full combustion correspondence period CP coincides with a constant target full combustion correspondence period CPtgt.

A collimator lens 4 corrects a third-order spherical aberration which is generated depending on the thickness of a light transmissive layer from a surface of a first optical information recording medium 30, corresponding to an optimal substrate thickness of a first objective lens 6, to an intended information recording surface, assuming that the light transmissive layer thickness of the first optical information recording medium 30 which minimizes a residual third-order spherical aberration at the time of incidence of parallel light into the first objective lens 6 is defined as the optimal substrate thickness of the first objective lens 6. The optimal substrate thickness of the first objective lens 6 is defined in such a manner that a variation of a wavefront aberration which is generated on the information recording surface of the first optical information recording medium 30 farthest from the first objective lens 6 at the time of correcting the third-order spherical aberration, and a variation of a wavefront aberration which is generated on the information recording surface of the first optical information recording medium 30 closest to the first objective lens 6 at the time of correcting the third-order spherical aberration are set equal to each other. |
