Wolfram Demonstrations Project

Drag the locators until all lines are non-intersecting (green).

This may not be hard with 10 nodes, but it can be quite a task with 30 or 40 nodes.

Controls:

"number" controls the number of nodes.

"new setup" creates a new configuration of nodes and lines.

"randomize" randomly shuffles the nodes, but keeps the associated lines.

"labels" displays the sequence numbers of the nodes.

"node size" controls the size of the locators.
