NettetLehmer (1951) introduced the simple congruence method, which is still used today. Sowey published three articles giving a classified bibliography on random number generation and testing (Sowey, E.R. 1972, 1978 and 1986). In 1996, Dodge, Yadolah proposed a natural method of generating random numbers from the digits after the … NettetThe most common method of generating pseudo-random numbers on the computer uses a recursive technique called the linear-congruential, or Lehmer, generator. The sequence is defined on the set of integers by the recursion formula or, in binary, (1) 138. Monte Carlo to form the normal number
