discretechoosersextension's Introduction

The NetLogo Discrete Choosers Extension (`dc`)

This is a NetLogo extension aiming to make the library of discrete choice algorithms developed by Ernesto Carrella easily usable from within NetLogo.

See http://carrknight.github.io/poseidon/algorithms.html for a discussion of the different algorithms available.

This extension is still in the early stages of development. Not all algorithms are available, and those that are might still be buggy. Feedback and bug reports are welcome. (Just open an issue.)

You can download the extension from the releases page. Just unzip dc.zip under your NetLogo extensions/ folder. Once it's a bit more stable, I'll make it available through the NetLogo Extensions Manager.

The extension requires NetLogo >= 6.0.0.

Rudimentary demo models are available in the demo/ folder.

Build test cases

Ernesto suggests using this paper as a test case:
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5112854/

Provide primitive to extract most highly valued choice

For the epsilon greedy bandit, it would be the equivalent of:

to-report final-choice [ bandit ]
  dc:set-epsilon bandit 0
  dc:update-choice bandit
  report dc:last-choice bandit
end
