Abstract

Simulation and mathematical modelling of how memory length and degree of self-interest change outcomes in the iterated prisoner's dilemma, framed around implications for AI agent design.

Why it worked
ResearchForge's reading of the public record — not the students' words, and not the judges' reasoning.

Two parameters, varied systematically, in a game whose baseline behaviour is already well understood. Working inside a canonical problem means every result has something to be compared against.

Key methods
  • Iterated prisoner's dilemma simulation
  • Memory-length parameter sweep
  • Self-interest parameter sweep
  • Mathematical modelling of strategy outcomes
What to take from this
ResearchForge's reading of the public record — not the students' words, and not the judges' reasoning. Borrow the habits and decisions, never the project itself.
  • A well-studied model is a gift: your result immediately has a reference point
  • Varying two parameters across their range beats testing two hand-picked configurations

Archive entries are summaries compiled for study. Read them for how a project was structured, argued, and defended — not as a template to reproduce. Copying someone else's project is the one thing that will end yours.

Compiled by ResearchForge from the Society for Science public award announcement linked on this record. Names, hometowns, project titles and reported results are as published. The "why it worked" and "what to take from this" notes are ResearchForge's editorial reading of that public record — they are not statements by the students and not the judges' rationale.
