Why is OR applicable to sports?
Many sports have a score, a number, to be maximised or optimised - hence there is a link to OR
Most sports have limited resources, to be used optimally - hence OR, The resources may be the team, or time, or money
Many sports operate sequentially, with decisions being made in order - just like in dynamic programming
Sports events require transport and supply chains - areas where OR has expertise
In a separate blog, I have mentioned the range of sports which have provided abstracts in IAOR. Most of those links are to strategy in the sport itself. My other blog on the subject considers the problems of scheduling transport.
