*Three questions that researchers frequently ask to quantify the
complexity of the thing (house, bacterium, problem, process, investment
scheme) under study are*

*1. How hard is it to describe?*

*2. How hard is it to create?*

*3. What is its degree of organization?*

*Here is a list of some measures of complexity grouped according to the
question that they*

*try to answer. Measures within a group are typically closely related
quantities.*
