Graph algorithms operation an graphs in any representation.

# #

Graph algorithms which do not specify a particular approach for representing a Graph.

Functions in this package will take arguments that provide the mechanism for traversing the graph. For example two common approaches for representing a graph:

```
class Graph {
Map<Node, List<Node>> nodes;
}
class Node {
// Interesting data
}
```

```
class Graph {
Node root;
}
class Node {
List<Node> children;
// Interesting data
}
```

Any representation can be adapted to the needs of the algorithm:

- Some algorithms need to associate data with each node in the graph and it will
be keyed by some type
`K`

that must work as a key in a`HashMap`

. If nodes implement`hashCode`

and`==`

, or if they are known to have one instance per logical node such that instance equality is sufficient, then the node can be passed through directly.`(node) => node`

`(node) => node.id`

- Algorithms which need to traverse the graph take a
`children`

function which provides the reachable nodes.`(node) => graph[node]`

`(node) => node.children`

Graphs which are resolved asynchronously will have similar functions which
return `FutureOr`

.
