Directed sets are mathematical structures that consist of a set equipped with a preorder relation, denoted by $\geq$, which satisfies the condition that for any two elements within the set, there exists another element that is greater than or equal to both.

This defining property ensures that for any pair of elements, one can find a common successor within the set, thereby providing a sense of direction.

In the realm of directed sets, the concept of maximal elements plays a crucial role. A maximal element is defined as one that has no other element strictly greater than it within the set. This should not be confused with the greatest element, which is an element that is greater than or equal to every other element in the set. It is important to note that within directed sets, every maximal element automatically qualifies as a greatest element due to the inherent properties of these structures.

The practical application of directed sets can be observed in the linearizations and chunkings of graphs or clusters. These processes involve organizing the elements of a graph or cluster into a sequence or partition that adheres to the preorder. The merge-intersection algorithm is a computational method used for identifying the common successor element 'c' given any two elements 'a' and 'b'. Furthermore, there is a specific algorithm designed to optimize the process of finding maximal elements. This algorithm operates by prioritizing the subset with the highest feerate and continues processing the remaining elements.

The term "optimal linearization" refers to the process of determining the greatest element in the context of directed sets. This involves identifying an element that stands as the upper bound for all elements within the set, thus achieving the most efficient ordering or grouping. The significance of optimal linearization lies in its ability to provide a structured and well-ordered representation of data, which can have various applications in computational and theoretical contexts.
