Emergent Communication with Stack-Based Agents

This repository contains the code for the paper "Emergent Communication with Stack-Based Agents," which has been accepted at Cognitive Science 2024.

Erratum Note

We found a minor omission in the paper's description of Algorithm 1 ("Calculate action sequences in complete-binary-branching baseline").

• Location: After line 4 (the first while condition), the following lines should be added:

    if shiftCount ≥ messageLen then
        A.append(REDUCE)
        continue
    end if

Note: This issue was only present in the paper's algorithm description. The original implementation provided in this repository was correct. Therefore, this minor omission does not affect experimental results or conclusions. We apologize for any confusion caused.
