From the eyes and mind from outside of LODA and OEIS and mathematical sequences... So what is this all about?! Sorry, but the present front page description leaves out a few essential details for those that do not already know all about this! From the front page and the threads, my present guess is:

Proposals for improved texts for the website are much welcome. I'm not a native english speaker, so explaining what LODA is about, in a easy readable way, is hard for me. Below is my attempt at describing what LODA is.  LODA is a math AI, that takes integer numbers as input, and outputs a corresponding formula. LODA needs your help training the AI. Please join the BOINC community for this. Is LODA correct? No, is the short answer. The long answer, it depends on the training data. The OEIS database is used as training data. There is math everywhere, such as crystal structures, how many spheres can be fitted in a cube, how quickly can rabbits multiply. If LODA find a new formula that does things in a smarter way, that what was previously known, it may lead to new discoveries in the field of math/physics. It may reduce power consumption in computers.

Proposals for improved texts for the website are much welcome. Really? Is an AI system used to generate and to test the programs/LODAdescriptions? Or is this a brute force "try all permutations" or "follow a simple generate algorithm" that are typical of a 'mining' brute force search? Taking your description and this overview: https://lodalang.org/ wrote: LODA is an assembly language, a computational model, and a distributed tool for mining programs. You can use it to generate and search programs that compute integer sequences from the OnLine Encyclopedia of Integer Sequences® (OEIS®). The goal of the project is to find new formulas and more efficient algorithms for a wide range of nontrivial integer sequences. ... one possible description might be: This Boinc project looks for LODA programs ('formulae') that more efficiently generate integer sequences such as the digits of pi, or the list of prime numbers... And many others already known and those yet to be found. Integer sequences are of great interest in mathematics and they are also a fundamental part of everyday life. We have the Fibonacci sequence, for just one popular example, that can be seen in the optimal arrangement of leaves on a plant stem, or in the arrangement of the seeds in a sunflower, or for how your bones grow. Further beyond life, this sequence is marvelously strung throughout science and human culture and art and beyond. And there are an infinity of other sequences... The LODA programs that are generated are tested against the OnLine Encyclopedia of Integer Sequences® (OEIS®). LODA offers methods that may be able to more efficiently generate integer sequences and to allow us to better understand those sequences. The LODA programs that we find may also be used to speed up generating those sequences so that we can make computers run faster for lower power. You can help with this project. Welcome to a deep search! Keep searchin' Martin

Martin, your explanation is spot on. I may copy parts of it. ML algorithms. Currently it's brute force, trying mutating existing programs and see if the candidate program is an entirely new program, or an improvement to an existing program. In LODARUST uses: bloomfilter, pagerank, ngrams, Localitysensitive_hashing. This is what the "trigram.csv" with instructions look like count;word0;word1;word2 20976;lpe;mov;STOP 17672;add;lpe;mov 15456;mov;lpb;sub 14987;START;mov;mov 11889;mov;mov;lpb 11836;lpb;sub;add 11041;lpb;sub;mov 10899;START;mov;add 9100;add;add;add 9094;add;lpb;sub 9062;sub;lpe;mov 8906;START;add;mov 8405;START;mov;lpb 8346;mov;add;lpb SNIP 4100 rows SNIP I want to experiment with transformers. I'm not sure how to represent the instructions/registers/values.

Martin, your explanation is spot on. I may copy parts of it. You're very welcome to copy as is or just parts, no credit needed/wished. ML algorithms. Currently it's brute force, trying mutating existing programs and see if the candidate program is an entirely new program, or an improvement to an existing program. Mmmmm... Machine Learning is not necessarily "Artificial Intelligence" (despite what the popular press get confused with!). Are you not describing the use of Genetic Algorithms? Or are you trying multiple heuristics?... If using a brute force tryallpermutations: What will be the estimated rate of progress? Or is such a simple method good enough to quickly give good results? Good project! Thanks, Martin
