Feature Comparison with Other Electoral Simulators

Research findings: features from other open-source electoral simulation projects that may inform ElectoralSim's roadmap.

Johnh865/election_sim

  • Electoral college simulation (US-focused)
  • Interactive web-based exploration
  • Swing state sensitivity analysis
  • Potential features to adopt: Electoral college weight model, swing state analysis

endolith/elsim

  • Python-based electoral simulation
  • Gerrymandering analysis focus
  • District drawing and efficiency gap measurement
  • Potential features to adopt: Advanced gerrymandering metrics, district-level efficiency gap

ElectionSim (arXiv)

  • Academic paper describing multi-agent electoral modeling
  • Focus on emergent behavior in multi-party systems
  • Uses agent-based approach similar to ElectoralSim
  • Potential features to adopt: Enhanced multi-party dynamics, emergent party system formation

es_simulations

  • Lightweight electoral system comparison
  • Web-based visualization
  • Potential features to adopt: Side-by-side system comparison UI

ALEX4

  • Advanced legislative election modeling
  • Seat allocation with multiple tiers
  • Potential features to adopt: Multi-tier electoral systems (e.g., German MMP modeled more precisely)
