What is the purpose of listing the second condition (The job times must be mutually exclusive of the job sequence) if you've already said that job times must be constant (the first condition) or am i missing something? —Preceding unsigned comment added by 72.48.91.143 (talk) 04:13, 16 September 2008 (UTC)
The final answer in the example is given as CEADB, whereas, it should be CADEB as per the rule. Sony 59.91.244.212 (talk) 13:30, 3 June 2010 (UTC)
