"Nettetmaxproblem, Johnson (1954) gave a decision rule, now popularly called Johnson’s rule: For any two jobs J i,J j∈ N, if min{p i,q j} ≤ min{q i,p j}, then schedule job J i earlier than job J j. Based on this rule, a solution algorithm, known as Johnson’s algorithm, can be designed, which has a time complexity of O(nlogn). " - Johnson's rule scheduling
