41Dempster–Shafer theory — Prof Arthur P. Dempster at the workshop on Belief Function Theory (Brest 1 april 2010). The Dempster–Shafer theory (DST) is a mathematical theory of evidence.[1] It allows …
42Equivalence class — This article is about equivalency in mathematics; for equivalency in music see equivalence class (music). In mathematics, given a set X and an equivalence relation on X, the equivalence class of an element a in X is the subset of all elements in… …

47Petri net — A Petri net (also known as a place/transition net or P/T net) is one of several mathematical modeling languages for the description of distributed systems. A Petri net is a directed bipartite graph, in which the nodes represent transitions (i.e.… …
48Bipartite graph — In the mathematical field of graph theory, a bipartite graph (or bigraph) is a graph whose vertices can be divided into two disjoint sets U and V such that every edge connects a vertex in U to one in V ; that is, U and V are independent sets.… …
49Mutually exclusive events — For the programming algorithms, see Mutual exclusion. In layman s terms, two events are mutually exclusive if they cannot occur at the same time. An example is tossing a coin once, which can result in either heads or tails, but not both. In the… …
50Semiring — In abstract algebra, a semiring is an algebraic structure similar to a ring, but without the requirement that each element must have an additive inverse. The term rig is also used occasionally this originated as a joke, suggesting that rigs are… …
