A different view of direct reciprocity in the evolution of cooperation. The enduring strategy in an evolving population need not be discriminators if unconditional cooperators can occasionally mutate to a conditional strategy in presence of defectors.

Stabilizing unconditional cooperation | Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences
The ultimate goal of research on the evolution of cooperation could be conceived as
finding a method for stabilizing strategies that always cooperate, that never deviate
from cooperation, that never e...

I mean, as someone whose life's work has been developing general mathematical theory for evolution, I do think there is some scope to do theory in a general way, while still acknowledging the limits of its applicability link.springer.com/article/10.1...
A mathematical formalism for natural selection with arbitrary spatial and genetic structure - Journal of Mathematical Biology
We define a general class of models representing natural selection between two alleles. The population size and spatial structure are arbitrary, but fixed. Genetics can be haploid, diploid, or otherwi...

Asymptotic Extinction in Large Coordination Games
We study the exploration-exploitation trade-off for large multiplayer coordination games where players strategise via Q-Learning, a common learning framework in multi-agent reinforcement learning. Q-L...

In a new paper published today, @yohm.bsky.social and I discuss a general framework to make sense of social norms and different indirect reciprocity models. Below is a 🧵, here is the paper:

🚨The evolution of forecasting for decision-making in dynamic environments🚨
We explore a middle ground between rational economic and myopic evolutionary theories, when decisions feedback on environmental states.
