摘要： Computer systems attempt to manage resource pools of a dynamic number of similar resources and work tasks in order to optimize system performance. Work requests are received into the resource pool having a dynamic number of resources instances. An instance-throughput curve is determined that relates a number of resource instances in the resource pool to throughput of the work requests. A slope of a point on the instance-throughput curve is estimated with stochastic gradient approximation. The number of resource instances for the resource pool is selected when the estimated slope of the instance-throughput curve is zero.

摘要： A controller in which proportional integral (PI) arithmetic is effected on a deviation between a measurement or process signal from a process or controlled system and a control set value, and a resultant manipulation signal is outputted to the process. A waveform of the process signal or the deviation signal is observed. PI arithmetic parameters undergo self-tuning so that the measurement result becomes a preset response target. In the preferred embodiment, means are provided for performing self-tuning on the PI arithmetic parameters including waveform observing means for using an area ratio of a first area to a second area as one of the evaluation indexes which represent patterns of the measured waveforms, the ratio being associated with the process signal or the deviation signal extending from a first generation timing of a first peak of the process signal or the deviation signal, to a subsequent second generation timing of a second peak, the second area being associated with the process signal or the deviation signal extending from the second generation timing to a timing given by second timing+(second timing - first timing).

摘要： The invention relates to the production of an optimum value of a system output function which is dependent upon a plurality of variables where the effect of changes in the variables upon the function may be determined. An optimum is reached quickly and efficiently by changing each variable repetitively in a random manner initially and thereafter the tendency of the changes to be purely random is modified so that past history in the search for the optimum value tends to weight the randomness in favor of the most desirable direction toward optimum.

摘要： A system and method more accurately solves equality-constrained a quadratic program without significantly increasing computational load. The solver can be used to iteratively determine the solution to a general quadratic program via an active set method. The algorithm determines which of the equality constraints are binding and which constraints are not. The non-binding constraints are dropped from the active set and the objective function improved. The non-binding constraints are identified based upon the signs of the Lagrange multipliers of the equality constraints. The algorithm determines the optimization variables and the Lagrange multipliers independently of one another based upon a single matrix factorization.
