# ALIFE: Artificial Life Comprehensive Skill **Status**: ✅ Production Ready **Trit**: +1 (PLUS - generative/creative) **Sources**: ALIFE2025 Proceedings + Classic Texts + Code Repos ## Quick Reference | Resource | Content | |----------|---------| | **ALIFE2025** | 337 pages, 80+ papers, 153 figures, 100+ equations | | **Axelrod** | Evolution of Cooperation, TIT-FOR-TAT, Prisoner's Dilemma | | **Epstein-Axtell** | Sugarscape, Growing Artificial Societies | | **ALIEN** | CUDA 2D particle engine (ALIFE 2024 winner) | | **Lenia** | Continuous cellular automata | | **Concordia** | DeepMind generative agent-based models | ## Core Concepts ### 1. Evolutionary Dynamics ```latex % Fitness-proportionate selection P(i) = \frac{f_i}{\sum_{j=1}^{N} f_j} % Replicator dynamics \dot{x}_i = x_i \left[ f_i(x) - \bar{f}(x) \right] ``` ### 2. Prisoner's Dilemma & Cooperation ``` Cooperate Defect Cooperate R,R S,T Defect T,S P,P where T > R > P > S (temptation > reward > punishment > sucker) ``` **TIT-FOR-TAT Strategy** (Axelrod): 1. Cooperate on first move 2. Then do whatever opponent did last round Properties: **Nice** (never defects first), **Retaliatory**, **Forgiving**, **Clear** ### 3. Cellular A
