Code:

Inputs:

Ember takes two files as input, the graph file and the lookup file used to indicate which nodes to embed.

Input graph file

The input graph file is the static edge list in the following format separated by tab:

<src> <dst> <weight>

The edge list is assumed to be re-ordered consecutively from 0, i.e., the minimum node ID is 0, and the maximum node ID is <#node - 1>. A toy static graph is under "/graph/" directory.

Input lookup file

The lookup file is a subset of nodes in the graph to embed. A toy example is under "/graph/" directory.

Other input argumets

The specific configuration to pass to EMBER can be found with the python main -h command.
