- N
`ElementType!Range`N`(Range values, Num totalSize)` Calculate the Nxx (e.g. N50) of values.

- absdiff
`Num`absdiff`(in Num a, in Num b)` Returns the absolute difference between two numbers.

- add
`G.Edge`add`(ref G graph, G.Edge edge)` Add an edge to this graph and handle existing edges with

`handleConflict`. The handler must have this signature`Edge handleConflict(Edge, Edge)`.- bulkAdd
`void`bulkAdd`(ref G graph, R edges)` Add a set of edges to this graph and merge mutli-edges using

`merge`.- ceil
`Integer`ceil`(in Integer x, in Integer base)` Round x upward according to base, ie. returns the next integer larger or equal to x which is divisible by base.

- ceildiv
`Integer`ceildiv`(in Integer a, in Integer b)` Returns the result of

`ceil(a / b)`but uses integer arithmetic only.- findAllCliquesauto findAllCliques
`(in size_t[][] adjacencyList)` Find all maximal cliques in a graph represented by

`adjacencyList`. The implementation is based on version 1 of the Bron-Kerbosch algorithm [1].- floor
`Integer`floor`(in Integer x, in Integer base)` Round x downward according to base, ie. returns the next integer smaller or equal to x which is divisible by base.

- longestIncreasingSubsequenceauto longestIncreasingSubsequence
`(Range sequence)` Calculate a longest increasing subsequence of

`sequence`. This subsequence is not necessarily contiguous, or unique. Given a`sequence`of`n`elements the algorithm uses`O(n log n)`evaluation of`pred`.- mean
`ElementType!Range`mean`(Range values)` Calculate the mean of range.

- median
`ElementType!Range`median`(Range values)` Calculate the median of range.

- Graphstruct Graph(Node, Weight = void, Flag!"isDirected" isDirected = No.isDirected, EdgePayload = void)
This structure represents a graph with optional edge payloads. The graph is represented as a list of edges which is particularly suited for sparse graphs. While the set of nodes is fixed the set of edges is mutable.
