A sparse ruler is a ruler in which some of the distance marks may be missing. More abstractly, a sparse ruler of length L {\displaystyle L} with m {\displaystyle m} marks is a sequence of integers a 1 , a 2 , . . . , a m {\displaystyle a_{1},a_{2},...,a_{m}} where 0 = a 1 < a 2 < . . . < a m = L {\displaystyle 0=a_{1}<a_{2}<...<a_{m}=L} .
