[Dprglist] On Behavior Trees [Was: self driving trucks and the desert]

[Rud Merriam]

I replied to David and included this link: 
https://www.gamedeveloper.com/programming/behavior-trees-for-ai-how-they-work

Here is a direct link to a C++ implementation I created: 
https://bitbucket.org/rmerriam/devr/src/master/robot/mystic_bt/include/

A python implementation: 
https://github.com/ToyotaResearchInstitute/task_behavior_engine Haven't 
looked at this in detail so caveat emptor.

Here is another more academic article which shows how subsumption is a 
/sequence/ in BTs:
