Kidney exchange provides a life-saving alternative to long waiting lists for patients in need of a new kidney. We derive a variety of mathematical models for the kidney exchange optimization problem, where the general goal is to maximize some form of social welfare vis-à-vis transplanting kidneys. We explore the implications of making the optimization problem dynamic (considering the future evo...
