SIAM Journal on Applied Mathematics, Vol. 34, No. 1 (Jan., 1978), pp. 176-197 (22 pages) We consider a graph-theoretic elimination process which models Gaussian elimination on sparse systems of linear ...

Acyclic directed mixed graphs (ADMGs) are graphs that contain directed (→) and bidirected (↔) edges, subject to the constraint that there are no cycles of directed edges. Such graphs may be used to ...

Discrete Mathematics is a subject that has gained prominence in recent times. Unlike regular Maths, where we deal with real numbers that vary continuously, Discrete Mathematics deals with logic that ...

Abstract: In the era of rapid advancements in energy, manufacturing, and aerospace, system modeling and simulation is essential across industries. Simulation technologies enable better control over ...

Abstract: This paper elaborates on the current situation and challenges of teaching discrete mathematics, pointing out that due to its high degree of abstraction, students often find it difficult to ...
