Workload of jobs in the inside-outside algorithm. The execution time is proportional to job height, as illustrated here for the (a) inside and (b) outside algorithms. Jobs executed last take longest (top job in inside algorithm, bottom row in outside algorithm). (The expectation value calculations are analogous to the inside algorithm, but each job takes comparatively shorter time.) The linear dependence on job height gives rise to the O(n3) time complexity.
