The rendezvous dilemma is related to the prisoner's dilemma and can be formulated in this way:
- Two young people have a date in a park they have never been to before. Arriving separately in the park, they are both surprised to discover that it is a huge area and consequently they cannot find one another. In this situation each person has to choose between waiting in a fixed place in the hope that the other will find them, or else starting to look for the other in the hope that they have chosen to wait somewhere.
Examples of this class of problem are known as rendezvous problems.
As well as being problems of theoretical interest, rendezvous problems include real-world problems with applications in the fields of synchronization, operating system design, operations research and even search and rescue operations planning.
