Labor-based Grading in Computer Science: A Student-Centered Practice Open
Innovation in teaching in STEM fields was explored widely during the COVID pandemic in 2020. This paper describes the adaptation of labor based grading for computer science courses. Labor based grading has been developed for language and w…
Domestication syndrome via indirect selection in simulated cereal grains Open
Domestication syndrome in cereal grains is commonly thought to be the product of domestication through a combination of direct artificial selection and indirect natural selection by humans. We propose an agent-based model of grain domestic…
Deterministic Response Threshold Models of Reproductive Division of Labor Are More Robust Than Probabilistic Models in Artificial Ants Open
We implement an agent-based simulation of the response threshold model of reproductive division of labor. Ants in our simulation must perform two tasks in their environment: forage and reproduce. The colony is capable of allocating ant res…
Reproductive division of labor in a colony of artificial ants Open
We simulate an ant colony in which an ant’s genetics can determine behavioral, morphological and physiological differences between workers and queens. We show that depending on the benefits conferred to workers and queens different reprodu…
Social Learning and Cultural Evolution in Artificial Life Open
We describe the questions and discussions raised at the First Workshop on Social Learning and Cultural Evolution held at theArtificial Life Conference 2016 in Cancún, Mexico in July 2016. The purpose of the workshop was to assemble artific…
Multilevel Selection Can Lead to Cooperation in a Public Goods Game Open
In the basic public goods game the Nash equilibrium is to defect, that is, to share nothing. Resource sharing can evolve via multilevel selection on groups that have low variation within the group ...
Divergent Cumulative Cultural Evolution Open
Divergent cumulative cultural evolution occurs when the cultural evolutionary trajectory diverges from the biological evolutionary trajectory. We consider the conditions under which divergent cumulative cultural evolution can occur. We hyp…
Finding a Mate With Eusocial Skills Open
Sexual reproductive behavior has a necessary social coordination component as willing and capable partners must both be in the right place at the right time. It has recently been demonstrated that many social organizations that support sex…
Modeling the Evolution of Gene-Culture Divergence Open
We present a model for evolving agents using both genetic and cultural inheritance mechanisms. Within each agent our model maintains two distinct information stores we call the genome and the memome. Processes of adaptation are modeled as …
