Hi, I'm Anatole V [Anatoly E. Voevudko, PhD], residing in the USA. My 1K bigger user page easy to find on OEIS Wiki. I was starting programming in the machine code for mainframe IBM 370. In last 2 decades I've created more then 30 websites (partially or in full). In addition, I've always been a scientist interested in AI. NT, etc. I've already contributed here on RC more than 75 solutions.
