DamerauLevenshteinDistance[u, v] gives the Damerau\[Dash]Levenshtein distance between strings or vectors u and v.
DistributionParameterQ[dist] yields True if dist is a valid distribution, and yields False otherwise.
FindVertexCover[g] finds a vertex cover of the graph g with a minimum number of vertices.
GroupCentralizer[group, g] returns the centralizer of the element g in group.
