What a wonderful thing to read on a morning I am supposed to write a discussion section.

ChatGPT is helping me do research on ChatGPT.
I have become the microscope.

Future work should study more general models in this direction. Happy to talk. Wishing everyone the best :)

The rescue strategy that arises from mutations is naturally selected away after defectors go extinct thereby restoring the unconditionally cooperating population. We analyze a simple finite and infinite population model and determine properties of an ideal rescue strategy.

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...

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.

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...

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...

Congrats Chadi! Great news :)

A mathematics joke! Glad to have left some influence.

Looking for a light read during the holidays?🎄 Let me tell you about our new publication with Vince Knight & @marcharper.bsky.social on the properties of strategies in computer tournaments for the Iterated Prisoner’s Dilemma (IPD) 🧵

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.
