New linear models on RDB
Yang Ke-chang · 2004
We established several new linear models on RDB.Let a ruler have n marks,and let its length be L.A set of models of marks distribution,each of which makes the ruler perfect,is denoted by f(len,n) Our main results are the following three linear models:f(8n-31,n)={1,4,5,8,8,…,8,3,1,2,1};f(9n-41,n)={1,4,3,4,9,9,…,9,5,1,2,2};f(10n-55,n)={1,1,3,4,10,10…,10,2,3,6,2,3} By the new models,in applicable range of n(n19),we improved the author's previous results,which were derived from the quadratic models.
