An optimized search strategy could be applied to situations as diverse as animal foraging and time-sensitive rescue missions. Operations research ¡X the field that uses mathematical methods to optimize complex real-world structures and processes ¡X grew out of the analysis of military problems during the Second World War. One such question was the optimization problem 'How to hunt a submarine'1, the analysis of which had to take several factors into account.
