His work focuses on enhancing the efficiency of computational methods, particularly in the context of linear systems and matrix operations.

Latest Patents

One of his latest patents is the "Preconditioned Conjugate Gradient System." This apparatus optimizes the operational state of a system following the Karmarkar method. It provides a solution to the linear system of equations AD²Aᵀu = p using a modified conjugate gradient method that incorporates a preconditioning operation. This operation includes pre-drop and post-drop procedures that judiciously discard values smaller than a certain threshold, thereby reducing the number of non-zero terms in the matrix. The use of this method significantly decreases the processing time required for each iteration in the Karmarkar method. Furthermore, improvements in operating speed are achieved by employing an asymmetric conjugate gradient method, which adjusts preconditioning parameters to eliminate the need for square root operations.

Another significant patent is the "Computation Optimizer." This method and apparatus efficiently perform preselected computations on data that changes infrequently. By recognizing that a portion of the data remains constant, substantial improvements in computation speed are realized. The apparatus tailors the program executing the computation to the data itself. In the context of multiplying a seldom-changing matrix by a frequently changing vector, this is accomplished by reordering elemental operations to reduce memory access for both reading and writing.
