Báo cáo toán học: "Optimal Token Allocations in Solitaire Knock ’m Down" ppt

... 2000 Abstract In the game Knock ’m Down, tokens are placed in N bins. At each step of the game, a bin is chosen at random according to a fixed probability distribution. If a token remains in that bin, it ... a token in bin j was the last one removed in the game. Consider the event τ i <T X . When this occurs, all of the tokens in bin i are gone before time τ i , but at...

... elementary construction using binary codes gives new record kissing numbers in dimensions from 32 to 128. 1. Introduction Let τ n denote the maximal kissing number in dimension n, that is, the ... 30,828. In this way we obtain a kissing number of 331,737,984. n=80. By taking 4 orbits under L 2 (79) we obtain A(80, 16, 16) ≥ 143,780. We take n 0 = 64, n 1 = 16, n 2 =4,n 3 = 1 and obtain...

... found in (b), by Theorem 3 there is no tight in nite family of nus integers containing the initial N 0 . Note that the condition w ≤ y given in Theorem 3 is not a restriction because if a given integer ... holds for in nite values of N , there are also another in nite set of integers with D(N) <D 1 (N). These other integral values of N are called non-unit step integers or nus intege...
