 Rice 2015 (see also 2012) focuses on optimality models, which are widely used in physics, biology and economics. He argues that these models explain without tracking any genuine causal structure in the target phenomenon. Such models give rise to “optimization explanations”. Baron 2014 considers a case of mathematical explanation in science concerning search patterns of fully-aquatic marine predators and argues that mathematical explanations in science are rather common on account of the widespread use of optimality models of statistical nature (such as Lévy walks displayed in the search patterns mentioned above). Baron 2016b also discusses the example in connection to the role idealizations play in such explanations (see also Potochnik 2007).
