Abstract:We show that provided urn:x-wiley:10429832:media:rsa20510:rsa20510-math-0001 we can with high probability find a collection of urn:x-wiley:10429832:media:rsa20510:rsa20510-math-0002 edge‐disjoint Hamilton cycles in urn:x-wiley:10429832:media:rsa20510:rsa20510-math-0003, plus an additional edge‐disjoint matching of size urn:x-wiley:10429832:media:rsa20510:rsa20510-math-0004 if urn:x-wiley:10429832:media:rsa20510:rsa20510-math-0005 is odd. This is clearly optimal and confirms, for the above range of p, a conjecture of Frieze and Krivelevich. © 2013 Wiley Periodicals, Inc. Random Struct. Alg., 46, 397–445, 2015
