Thanks, that makes sense. I was thinking that the diagrams represented all the nodes that the agents looked at, and that based on what nodes they saw they would pick one to surgically set. I didn't realize they represented the result of setting a node.

Follow-up stupid questions:

  1. Do all the agents start with the same graph and just pick different surgery points, or is it a combination of starting with different nodes and picking different nodes?
  2. If you put "innards" and "platonic" on the same graph (for any reason) what does that look like?

  1. They have different graphs, but the one necessary difference is the node that they do surgery on.

  2. Presumably you would remove the arrow from platonic algorithm to your action and add arrows from platonic algorithm to your innards and from your innards to your actions.
