why not just create an online API for this? Sequences that are not yet &quot;found&quot; would go uncompressed, and as time goes by and internet speeds get faster and computing power gets cheaper, more sequences will be &quot;found&quot; for reference in that API and the algorithm will keep getting better.<p>Alternatively, you could release a program that comes with an already long sequence of the decimal section of PI and connects regularly to the internet to download more digits (you could even run the computation &amp; API on a google compute &#x2F; amazon ec2 instance to keep costs low)
