In the area of artificial intelligence, which aims to let computers imitate or excel the human thinking, I have been studying several topics related games or puzzles and developed several computer programs.
My recent topics are:
Tsuitate-Shogi (Screen Shogi: variant of Japanese chess like screen chess)
3D board game Score Four.
Some developed programs of puzzles or games are available on the web.
Two-Times Sorting Sequence is generated as follows.
Starting a certain positive integer, for instance, in case starting from 1, numbers are doubled successively as follows.
1 → 2 → 4 → 8 → 16
After doubling, the digits of each number in decimal are sorted ascendingly. Therefore, the continued sequence are:
16 → 32 (sorted ascendingly) 23 → 46 → 92 (sorted ascendingly) 29 → 58
I have shown that all the Two-Times Sorting Sequences result in cycles. The computer program for generating all sequences is available.
