A state event detection algorithm for numerically simulating hybrid systems with model singularities
Joel M. Esposito, Vijay Kumar
Article No.: 1
This article describes an algorithm for detecting the occurrence of events, which signify discontinuities in the first derivative of the state variables, while simulating a set of nonsmooth differential equations. Such combined-discrete continuous...
An efficient single-pass trace compression technique utilizing instruction streams
Aleksandar Milenković, Milena Milenković
Article No.: 2
Trace-driven simulations have been widely used in computer architecture for quantitative evaluations of new ideas and design prototypes. Efficient trace compression and fast decompression are crucial for contemporary workloads, as representative...
Conversion of high-period random numbers to floating point
Jurgen A. Doornik
Article No.: 3
Conversion of unsigned 32-bit random integers to double precision floating point is discussed. It is shown that the standard practice can be unnecessarily slow and inflexible. It is argued that simulation experiments could benefit from making better...
On the theoretical comparison of low-bias steady-state estimators
Hernan P. Awad, Peter W. Glynn
Article No.: 4
The time-average estimator is typically biased in the context of steady-state simulation, and its bias is of order 1/t, where t represents simulated time. Several “low-bias” estimators have been developed that have a lower...
