Main Publication on IT:

• R. J. Chen, K. S. Reschke and H. Hu, " Design and Analysis of a Tree-Backtracking Algorithm for Multiset and Pure Permutations ," International Workshop on Combinatorial Algorithms ( IWOCA 2012 ), Kalasalingam University, India, LNCS 7643, pp. 288-292 , July 19-21, 2012. Open-source Code

We mathematically proved our combinational coding are the current fastest in the world. The previous fastest was authored by Robert Sedgewick, the William O. Baker Professor of Computer Science and Chairman of the Computer Sience Department at Princeton U. His "Algorithms" book was the best-selling algorithm text in the world.

This is my highest achievement, presenting with 40-minutes-speeking and 20-minutes-QandA for about 35 scientists at NASA`s Goddard Space Flight Center Information Science Department on 12-04-2001, and then in UK (Cambridge U and Liverpool U) and Italy (UKSIm 4th European Modelling...).

Luckily, a few weeks after my NASA presentation, I was invited to The USA NAVY Research Center for my workflow coding skills ......

--- Note: R. M. Havira was the VP (tech) of the company for decades

Authored (editor-in-chief ) a database textbook in 1988

Note: Projects always have something new; however, I could adapt myself quickly to the new teams/skills and always made products work very well to satisfy our Customers.
