What is the complexity of a dynamical system, of a swarm of robots, or of the economy? Scientists have been developing measures of complexity ever since they began to study complex systems. These measures use different mathematics, ranging from complex network theory, statistics of time sequences, to information theory and computational theory. Looking closer at these measures one finds that no size fits all. I will explain what these measures can and cannot do and how important it is to understand the features which make a system complex in order to quantify its complexity.
