WebApr 12, 2024 · To enforce some basic properties such as acyclicity in the relational graph, we add additional constraints to the optimization process, converting NAS into the problem of finding a Maximal Weighted Acyclic Subgraph (MWAS). Our algorithm then strives to eliminate cycles and only establish edges in the graph if the rank results can be trusted. WebThe usual name for such a digraph is directed acyclic graph (DAG). Multitrees are DAGs in which there are no two distinct directed paths from the same starting vertex to the same ending vertex. Oriented trees or polytrees are DAGs formed by orienting the edges of trees (connected, acyclic undirected graphs).
