Welcome to my new web page. This page will continue to host the benchmarks from the 1990's that used to reside under If you are browsing for these benchmarks, please proceed by clicking here.

I have worked for nearly 20-years in industry while also affiliated with a number of universities in Canada, North Carolina, Germany, Slovenia, Saudi Arabia, and Brazil. In 1986 I initiated, then continued as a General Chair until 1992, the International ACM Workshop Series on Layout and Logic Synthesis, held yearly at MCNC, Research Triangle Park, NC (with about 150 attendees from Americas, Europe, and Asia). This trend-setting series of workshops was a follow-up on the innovative organization of IEEE special sessions at ISCAS85 (Kyoto, Japan) and at ISCAS89 (Seattle, WA); both sessions were associated with distributions of challenging test generation benchmarks, now known under these acronyms. As of October 2021, there are $O(807,000)$ and $O(1,110,000)$ search engine hits for each of these two acronyms alone. A world-wide following from other special interest groups, including the NSF-sponsored DIMACS series of workshops, ensued in 1990's.

Since 2000, I have been actively engaged in promoting a more disciplined approach to performance testing of combinatorial algorithms. Particularly, the use of graph isomorphs did expose large performance runtime variability of competing algorithms and thereby did enable rigorous statistical runtime performance testing of the underlying solvers. Our experiments with hard combinatorial problems in different domains continue to demonstrate the intrinsic merits of a statistical model that reliably predicts the asymptotic runtime complexity of any solver -- provided that the solver is tested, without censoring, on a well-defined family of instances of increasing size.
