Rules

• Our games are rules based–board games–experimental games–models (ABMs and statistical)

• Our interest is in rules within social systems–rules for social systems

• (SES), game theory, communication, etc.

What is a rules engine?• Declarative programming model• Traditional if ... then structure• Excellent for modeling state changes

rule “name”when <condition,conditions>then <action, actions>

• Allow for modification of rules in context• turn by turn• game by game• session by session

• Can be created adaptively• based on input from game participants• modifications by researchers• even data-driven
