L algorithm

The L algorithm is an efficient algorithm for learning regular languages from positive examples. It was developed by Dana Angluin in 1987, and it is one of the most important algorithms in the field of inductive inference.

The L algorithm works by iteratively generating a series of hypotheses about the target language. Each hypothesis is a regular language that is consistent with the positive examples that have been seen so far. The algorithm then tests each hypothesis on a new set of positive examples. If the hypothesis is incorrect, then the algorithm generates a new hypothesis that is more general than the previous one. This process continues until the algorithm finds a hypothesis that is consistent with all of the positive examples.
