Comment (by asn):

 Replying to [comment:3 mikeperry]:
 > Some issues I've noticed:
 > 1. guard.is_targeted should be updated every time we change guards in a
 higher layer

 Hmm, we are supposed to do this in `self.is_targetted =
 self.is_targetted_func()` when we instantiate a new guard node... Logic
 seems solid, but code might be broken. Will look more into this.

 > 2. The graphs of G1 look suspicious (high CDF in low timescales for
 wimpy adversaries)

 Hmm, I just pushed a commit that should improve the situation here. Now
 the CDFs look more close to what they should be. But there are probably
 more bugs!

 > 3. The "none" adversary still takes a long time. Can we have a mode of
 the sim that stops at guard discovery for particularly weak adversaries?

 Still haven't done this one yet!
