Abstract
The author defined reincarnation-like phenomena as having continuousness in memory, personality traits, habits, etc. between a certain person and another certain deceased person, and discussed the super-psi hypothesis and survival hypothesis from the aspects of predictability and the limit of the algorithm. The super-psi hypothesis is considered as having suitable predictability. However, if higher factors such as intuition ability, not only data such as memories, are transferred to a new person from a deceased person, it is considered that some mechanisms are needed (including the survival hypothesis) which keep systems of personality traits, etc.
