Description
Theorem 2 as a word RAM program. Read the word, sort the jobs by start time, and fill the table of Section 3 over sets of thresholds written as base- numbers: the numbers are visited from the top, each is decided to be a code of a set or not by a recurrence, and the two sets , of recursion (1) are found by one scan of its digits (, independent of ), after which its cells cost each. The sets contribute in all. The table is the monotone one ("weight at least "), so it has rows whatever the weights are, and the answer is one entry of the column of the first indices. The domain restricts to positive processing times, the paper's standing assumption for Lemma 1's recursion. The running time is : no work per machine beyond the scan of a set.
