Statistical physics has proven to be valuable for better understanding counterintuitive evolutionary outcomes. By treating evolutionary games akin to classical spin models, a physicist can draw on experience and knowledge from familiar models in classical physics. However, unlike pairwise interactions among particles that typically govern solid-state systems, interactions among living organisms often involve groups, and they also involve a larger number of possible states even for the most simplified description of reality. The complexity of solutions observed in evolutionary games therefore often surpasses that observed in classical physical systems.

Submissions are invited for a Topical Issue of EPJ B on Extreme Value Statistics and Search in Biology: Theory and Simulations.
The reliability of the functioning of biological systems is still puzzling taking into account that many processes governing this functioning are prone to strong fluctuations on very different scales. In many cases these processes rely on a single or a few events, for example, those starting a signalling cascade, and may be dominated by the first or the first successful encounter of the corresponding units. Such encounters are often modelled as different variants of random search processes. The analysis of such processes pertinent to specific biological situations shows that in many cases a search process by a single agent is extremely ineffective, with typical encounter times considerably larger than what is necessary from the biological point of view. Therefore, the successful encounters are rare events.
