Quantifying the complexity of a system

    Are there generally accepted methods for quantifying the complexity of a system, enabling comparison and the requirements for quantitatively modeling it? Think everyone would agree that in complexity, for example a double pendulum is less complex than the global climate which is in turn less complex than an animal brain, but is there a useful way to quantify this?

    More along the lines of computational complexity. one measure would be perhaps the length of the algorithm needed to model it?

    Yes thanks, does this get used at all on biological systems? Wonder how a bacteria would come out
