Multi-agent simulation was used to study several styles of leadership in small societies. Populations of 50 and100 agents inhabited a bounded landscape containing a fixed number of food sources. Agents moved about the landscape in search of food, mated, produced offspring, and died either of...

Discrete agent simulation was used to study the role of reciprocity and normative reputation in the development of mutual obligation in gift-giving societies. Measures of economic and non-economic rewards were tracked over many generations of agents acting within a fixed environment and...

Discrete agent simulations were used to study the effects of alternate ethical systems on the development of individuals and societies. Agents with needs for food, rest, companionship, and activity were placed in a two dimensional artificial world with food centers, shelters, and material...

Discrete agent simulation was used to study several models of reciprocity and sanctions in a model egalitarian society. We found that mutual obligation between agents was maximized for indiscriminant sharing, the same condition that has been observed in several traditional cultures. Alternate...

Discrete agent simulation was used to investigate the role of violence and revenge in model egalitarian societies. A population of 100 agents inhabited a landscape of 20x20 squares containing five sources of food. Agents moved about the landscape in search of food, shared, stole, mated, produced...

Multi-agent simulation was used to study the effect of simple models of leadership on interpersonal violence and warfare in small societies. Agents occupied a two dimensional landscape containing villages and food sources. Sharing and stealing contributed to normative reputation. Violence...
