# Identify the sequence

(Might be a spoiler)

I was working on a famous problem, and I came up with a variation that can produce a sequence much harder to recognise than the original sequence.

Identify the problem which generates this sequence:

1, 1, 1, 2, 2, 2, 3, 4, 4, 5, 7, 8, 9, 12, 15, 17, 21, 27, 32, 38, 48, 59, 70, 86, 107, 129, 156, 193...

Hint:-

Fibonacci
