The State of Seqsee

I am relieved to have reached a stage where Seqsee sees all the sequences that I wanted it to see in the initial release. This does not mean that the work is done. It is still a long way home.

So what sequences can it see? If you allow me to include sequences that it sometimes sees, it is a long list. Many of these it can reliably extend, and making Seqsee reliable on the other sequences is the main work left.

The sequences:

• 1, 2, 3, 4…
• 1, 1, 2, 2, 3, 3, 4, 4…
• 1, 2, 2, 3, 3, 3, 4, 4, 4, 4…
• 1, 7, 2, 8, 3, 9…
• 1, 7, 1, 2, 8, 1, 2, 3, 9…
• 1, 1, 2, 1, 2, 3, 1, 2, 3, 4…
• 1, 1, 1, 2, 1, 1, 2, 1, 2, 3, 1, 1, 2, 1, 2, 3, 1, 2, 3, 4…
• 1, 1, 1, 2, 1, 3, 1, 4…
• 2, 1, 2, 2, 2, 2, 2, 3, 2, 2, 4, 2…
• 1, 2, 3, 2, 3, 4, 5, 3, 4,5, 6, 7…
• 1, 1, 2, 1, 1, 2, 3, 2, 1…
• 1, 17, 17, 1, 1, 1, 17, 17, 17, 17…
• 1, 1, 1, 2, 3, 3, 3, 4, 5, 5, 5, 6
• 2, 3, 5, 7, 11… (when primes are allowed in the domain via a switch)
• 2, 3, 2, 3, 4, 5, 4, 3, 5, 6, 7, 6, 5, 7, 8, 9, 10, 11, 10, 9, 8, 7…
• 1, 2, 1, 2, 3, 1, 2, 3, 4, 5, 1, 2, 3, 4, 5, 6, 7…
• 1, 2, 2, 3, 3, 5, 4, 7, 5, 11, 6, 13, 7, 17…
• 1, 2, 3, 17, 4, 5, 6, 17, 7, 8, 9, 17…
• 1, 2, 3, 17, 3, 4, 5, 17, 5, 6, 7, 17…
• 1, 1, 1, 2, 3, 2, 3, 2, 3, 4, 5, 6, 4, 5, 6, 4, 5, 6…
• 1, 1, 2, 3, 1, 2, 2, 3, 4, 1, 2, 3, 3, 4, 5…
• 1, 2, 3, 1, 2, 2, 3, 1, 2, 2, 2, 3…
• 1, 1, 2, 3, 1, 2, 2, 2, 3, 4, 1, 2, 3, 3, 3, 3, 4, 5…

Now that Seqsee has reached a feature-freeze, I will begin in earnest the task of fine-tuning. I have spent a long part of my work building tools, and these had better serve me well here.

I hope that this story does not end with me likened to George W. Bush when he said (five years ago!) “My fellow Americans: Major combat operations in Iraq have ended”. There are likely to be many surprises as I fine tune (and redo substantial chunks of various codelet families, remove accumulated cruft and so forth). That fine-tuning is a story unto itself, and it will get its own post.
