====== topic nodes ======

Topic nodes are high level nodes with proper names:

  * [[calculated data link]]
  * [[goal]]
  * [[goal group]]
  * [[simple_data_link]]

====== proxy-nodes ======

Proxy nodes stand in for and do the work of topic-nodes:

  * [[data link proxy]]
  * [[fuzzy curve]]
  * [[goal group proxy]]
  * [[goal proxy]]
  * [[switch]]

====== proxy support nodes ======

  * [[crisp argument]]
  * [[fuzzy argument]]
  * [[xy-pair]]

====== logic nodes ======

  * [[and]]
  * [[compare]]
  * [[crisp argument]]
  * [[data link proxy]]
  * [[false]]
  * [[fuzzy argument]]
  * [[fuzzy curve]]
  * [[goal group proxy]]
  * [[goal proxy]]
  * [[if]]
  * [[not]]
  * [[or]]
  * [[sor]]
  * [[switch]]
  * [[true]]
  * [[undetermined]]
  * [[union]]
  * [[xor]] 

====== conditional nodes ======

Conditional nodes can change the path of evaluation:

  * [[if]]
  * [[sor]]
  * [[switch]]

====== constants ======

  * [[e]]
  * [[error]]
  * [[false]]
  * [[k]]
  * [[pi]]
  * [[true]]
  * [[undetermined]]

  * [[ave]]
  * [[ceil]]
  * [[cos]]
  * [[cosh]]
  * [[deg2rad]]
