Memo on the Prediction Algorithm for the Moser-de Bruijn Sequence

Dear Team,

I am writing to provide an update on the development of our prediction algorithm for the Moser-de Bruijn sequence. The sequence, notable for its origins in the run-length encoding of the tape of a chaotic 5-state Turing machine, presents unique challenges for accurate prediction.

As you may know, the Moser-de Bruijn sequence is derived from a specific configuration of a Turing machine discovered by Marxen and Buntrock circa 1990. The machine operates in a chaotic manner, generating a binary sequence that, when subjected to run-length encoding, gives rise to the Moser-de Bruijn sequence.

We have developed a set of rules that allows us to predict transformations within this sequence with significant accuracy. Specifically, our current algorithm yields predictions that match the actual sequence 95% of the time. This level of accuracy is a testament to the efficacy of our approach and demonstrates the progress we have made in our understanding of this complex system.

Our method is based on maintaining, increasing, or decreasing the number of ‘1’ bits in the sequence, depending on their current position and the preceding sequence. We have also identified the need to alternate between two rules (which we call 3a and 3b) for handling ‘1’ bits in the third quarter of the sequence. This rule alternation appears to be crucial for maintaining high prediction accuracy.

While we are encouraged by these results, we recognize that there is always room for improvement and refinement. We are eager to continue testing and refining our algorithm, and we are exploring the possibility of introducing new rules that could further increase prediction accuracy. Additionally, we plan to test our model on a broad range of inputs to ensure its robustness and generalizability.

Thank you for your support as we continue this exciting and challenging work.

Best regards,

[Your Name]
