We're not trying to find out if two graphs are equal. Note that this isn't an isomorphism problem for labeled graphs. We define an equivalence relation this way: two nodes are equal if they contain the same value, they have the same number of outgoing edges, and, recursively, the subgraphs reachable from the two nodes following the outgoing edges in order are equal.Īs I explain further below, it's also OK but not a requirement for nodes to be equal if following their edges produces the same sequence of values. (That is, it's a k-ary tree, if such a term can be used for a cyclic structure). N, where N is the number of outgoing edges from the node). The outgoing edges of a node are ordered (or labeled 1, 2, 3. Nodes are not labeled, and different nodes can contain the same value. We have a directed graph, which can be cyclic, where each node contains a value. but it runs in quadratic time, making it impractical to use except for very small graphs. With some simplifying assumptions, a simple algorithm will also calculate hashes for nodes in a cyclic graph.

The reference i use for this is located at You'll find a library for handling this in Best regards, Hubert Posts: 93 Joined: 24. If i remember well, you would send: 1d 38 53 b8 9d (meaning left-ctrl-down left-alt-down del left-alt-up left-ctrl-up) or 38 1d 53 9d b8 (alt before ctrl).

I would also be happy if the solution was something else that came from someone who knows how the GUI console sends a Ctrl-Alt-Del to the guest. As far as I can tell, there is no scan code for the full combination, but I would be happy to be wrong. The scan code for Ctrl-Del is 0x8B and the scan code for Alt-Del is 0x98. I am hoping for a reply from someone who does knows how the command works for Ctrl-Alt-Delete, given that there does not appear to be a scan code for that key combination.
