The percentage of different operations of <i>OLTM</i> over time.

<p>The height of each color segment represents the percentage of an operation at a certain progress. “Op” is the abbreviation for “Operation” of <i>OLTM</i> at each step.</p

Two situations of a new edge linking two existing nodes.

<p>(a) Nodes belong to a same community; (b) Nodes belong to different communities.</p

Two operations to process a new edge linking a new node to an existing node.

<p>(a) A new node attaches to an existing node with degree two, it joins the same community as the existing node; (b) Another new node attaches to the previous new node with degree one, it splits as a new community.</p
