oriktade

Oriktade is a Swedish adjective meaning not directed or undirected. It is formed with the negating prefix o- attached to riktad, which means directed or oriented. The word is used mainly in technical contexts where orientation matters, such as mathematics, graph theory and computer science, to label objects that do not carry a fixed direction.

In mathematics and related fields, oriktade is commonly used to describe undirected structures. The most typical usage is oriktad graf, or an undirected graph. In an oriktad graf, edges connect two nodes without a specified direction, so the relation is symmetric: if node A is connected to node B, B is connected to A. This contrasts with riktad graf (directed graph), where each edge has a direction. The form is declined according to number: en oriktad graf (a single undirected graph) or flera oriktade grafer (several undirected graphs).

Outside graph theory, oriktade descriptions may appear in other domains to indicate lack of orientation or targeting, but the exact terminology can vary by field. In Swedish technical literature, the term is typically clear within its context and does not require further explanation for readers familiar with directed versus undirected concepts.
