The interface and the idea of ISA resembles OEIS which was created by Neil Sloane (former researcher at AT&T Labs). The main difference is that OEIS is a database, whereas ISA is a formula generator.
Since I am using a Raspberry Pi to host and run ISA, some heuristics might be useful to find common sequences more directly. But of course, in general only a tiny class of sequences can be automatically found in this way.
